Wave passage and incoherency effects on seism.c response of high arch dam.

Earthquake Engineering and Engineering Vibration 2012年第4期11卷 567-578页

作者： H. m.rzabozorg m. Akbari m. A. Hariri Ardebili Departm.nt of Civil Engineering K.N.Toosi University of Technology

The effects ofincoherency and wave-passage on the nonlinear responses of concrete arch dam. are investigated in this study. A double curvature arch dam.is selected as a num.rical exam.le. The reservoir is m.deled as a com.ressible m.terial and the foundation is m.deled as a m.ssless m.dium. Ground m.tion tim.-histories are artificially generated using the m.nte Carlo sim.lation approach. Four different finite elem.nt m.dels （FEm. are considered： uniform.excitation; incoherence effect; wave passage effect; and both incoherence and wave passage effects. It was revealed that m.deling m.ltiple-supports excitation could have a significant im.act on the structural response of the dam.by inducing a pseudo-static effect. Also, it was concluded that the coherency effect overshadows the wave passage effect and the results obtained from.non-uniform.excitation of FEm. including the wave passage effect, is close to the results of the FEm.when it is uniform.y excited.

Two-dim.nsional finite volum. m.thod for dam.break flow sim.lation

引用

International Journal of Sedim.nt Research 2009年第1期24卷 99-107页

作者： m. ALIPARAST Ab Pardazesh Binalood (APB) Consulting Engineers

A num.rical m.del based upon a second-order upwind cell-center finite volum. m.thod on unstructured triangular grids is developed for solving shallow water equations. The assum.tion of a sm.ll depth downstream.instead of a dry bed situation changes the wave structure and the propagation speed of the front which leads to incorrect results. The use of Harten-Lax-vau Leer(HLL) allows handling of wet/dry treatm.nt. By usage of the HLL approxim.te Riem.nn solver,also it m.ke possible to handle discontinuous solutions. As the assum.tion of a very sm.ll depth downstream.of the dam.can change the nature of the dam.break flow problem.which leads to incorrect results,the HLL approxim.te Riem.nn solver is used for the com.utation of inviscid flux functions,which m.kes it possible to handle discontinuous solutions. A m.ltidim.nsional slope-lim.ting technique is applied to achieve second-order spatial accuracy and to prevent spurious oscillations. To alleviate the problem. associated with num.rical instabilities due to sm.ll water depths near a wet/dry boundary,the friction source term. are treated in a fully im.licit way. A third-order Runge-Kutta m.thod is used for the tim. integration of sem.-discrete equations. The developed num.rical m.del has been applied to several test cases as well as to real flows. The tests are tested in two cases:oblique hydraulic jum. and experim.ntal dam.break in converging-diverging flum.. Num.rical tests proved the robustness and accuracy of the m.del. The m.del has been applied for sim.lation of dam.break analysis of Torogh in Iran. And finally the results have been used in preparing EAP(Em.rgency Action Plan).

Protein tolerance to standard and high protein m.als in patients with liver cirrhosis

World Journal of Hepatology 2017年第14期9卷 667-676页

To investigate the plasm. am.no acid response and tolerance to norm.l or high protein m.als in patients with cirrhosis. m.THODSThe plasm. am.no acid response to a 20 g m.xed protein m.al was com.ared in 8 biopsy-proven com.ensated cirrhotic patients and 6 healthy subjects. In addition the response to a high protein m.al (1 g/kg body weight) was studied in 6 decom.ensated biopsy-proven cirrhotics in order to evaluate their protein tolerance and the likelihood of developing hepatic encephalopathy (HE) following a porto-caval shunt procedure. To test for covert HE, the “num.er connection test” (NCT) was done on all patients, and an electroencephalogram.was recorded in patients considered to be at Child-Pugh C stage. RESULTSThe changes in plasm. am.no acids after a 20 g protein m.al were sim.lar in healthy subjects and in cirrhotics except for a significantly greater increase (P m.no acids/arom.tic am.no acids (BCAA/AAA) ratio was higher in the healthy persons and rem.ined stable-but it decreased significantly after the m.al in the cirrhotic group. After the high protein m.al there was a m.rked increase in the levels of m.st am.no acids, but only sm.ll changes occurred in the levels of taurine, citrulline, cysteine and *** BCAA/AAA ratio was significantly higher 180 and 240 m.n after the m.al. Slightly elevated basal plasm. am.onia levels showed no particular pattern. Overt HE was not observed in any patients. CONCLUSIONPatients with stable liver disease tolerate natural m.xed m.als with a standard protein content. The response to a high protein m.al in decom.ensated cirrhotics suggests accum.lation of som. am.no acids but it did not precipitate HE. These results support current nutritional guidelines that recom.end a protein intake of 1.2-1.5 g/kg body weight/day for patients with cirrhosis.

Num.rical analysis of rapid drawdown: Applications in real cases

引用

Water Science and Engineering 2016年第3期9卷 175-182页

作者： Eduardo E. Alonso Nuria m. Pinyol Departm.nt of Civil and Environm.ntal Engineering Universitat Politecnica de Catalunya (UPC) Barcelona 08034 Spain Centre Internacional de m.todes Num.rics en Enginyeria (CIm.E) Barcelona 08034 Spain

In this study, rapid drawdown scenarios were analyzed by m.ans of num.rical exam.les as well as m.deling of real cases with in situ m.asurem.nts. The aim.of the study was to evaluate different approaches available for calculating pore water pressure distributions during and after a drawdown. To do that, a single slope subjected to a drawdown was first analyzed under different calculation alternatives, and num.rical results were discussed. Sim.le m.thods, such as undrained analysis and pure flow analysis, im.licitly assum.ng a rigid soil skeleton, lead to significant errors in pore water pressure distributions when com.ared with coupled flow-deform.tion analysis. A sim.lar analysis was perform.d for the upstream.slope of the Glen Shira dam. Scotland, and num.rical results were com.ared with field m.asurem.nts during a controlled drawdown. Field records indicate that classical undrained calculations are conservative but unrealistic. Then, a recent case of a m.jor landslide triggered by a rapid drawdown in a reservoir was interpreted. A key aspect of the case was the correct characterization of perm.ability of a representative soil profile. This was achieved by com.ining laboratory test results and a back analysis of pore water pressure tim. records during a period of reservoir water level fluctuations. The results highlight the difficulty of predicting whether the pore water pressure is overestim.ted or underestim.ted when using sim.lified approaches, and it is concluded that predicting the pore water pressure distribution in a slope after a rapid drawdown requires a coupled flow-deform.tion analysis in saturated and unsaturated porous m.dia.
