目前我国地基沉降计算主要采用土压缩模量来计算,再用经验系数对计算结果进行修正。这种方法对于一些结构性较强的硬土地基误差较大,主要原因是取样扰动影响。为此,探讨了变形模量与地基承载力特征值的理论联系,在笔者提出的确定变形模量经验方法基础上,总结出依据地基承载力特征值确定变形模量的方法,该方法具有理论依据,可便捷地通过岩土工程勘察报告中常提供的地基承载力特征值确定土的变形模量,能够更为准确计算地基沉降值。采用不同方法(压板试验法、压缩模量推求法、标贯击数法、承载力经验法、依据地基承载力特征值确定变形模量法)计算了若干试验案例,通过对不同方法结果的对比,初步验证了依据地基承载力特征值确定变形模量法是可行的。

A typical Riedel Shear Pattern of active faults in the Laolongwan Basin， Northeastern Tibetan Plateau

＜正＞The shared risk link group （SRLG） has been widely recognized as an important concept in survivable optical networks. When some effective fault management mechanisms, such as path protection, are applied in optical networks, SRLG constraints should be taken into consideration. Although some SRLG-based path protection routing algorithms have been proposed, there are still several related problems have not been explored fully, such as the trap problem. Trap problem occurs frequently when finding SRLG-disjoint paths using some heuristic algorithms such as APF. In this paper, the concept of SRLG and Trap problem are introduced, and then a new method called sub-graph is used to improve the APF algorithm for trap avoiding. Simulation results show that the improved APF algorithm has a superior performance in terms of trap avoidance.

Riedel shear system， consists of some different oriented faults and derivative structures， is an important pattern of tectonic activity and stress regulation， which has been widely applied to the interpretation of intracontinental deformation. The Laolongwan Basin， located in the western Haiyuan fault zone at the northeastern Tibetan Plateau， is a key area to study the Cenozoic intracontinental deformation in the northeastern plateau， which formed a complex active fault system during the Cenozoic. However， the activity of these faults and their kinematic mechanism remain unclear. In this contribution， based on detailed structural interpretation of remote sensing image， field observations and OSL dating analysis， we propose a Riedel Shear model of active fault system in the Laolongwan basin. Our observations show that this active fault system is consist of four major faults， including the left strike-slip Hasi Shan Fault and Zihong Shan Fault with thrusting characteristics， the Southern Zihong Shan thrust fault and the Mijia Shan normal fault. The fault offset and OSL dating analyses suggest that the left-lateral slip rate of the Hasi Shan Fault is ～ 2.60-3.01 mm/a since ca. 15 ka， whereas the Zihong Shan Fault is ～ 1.10-1.13 mm/a since ca. 14 ka. Fault-slip vectors analyses indicate that the active fault system related to the Riedel Shear in the Laolongwan Basin was controlled by the regional ENE-WSW compressive stress. This compression also caused the significant left-lateral strike-slip movement along the Haiyuan Fault zone at the same time， which might result from the northeastward continuous expanding of the Tibetan Plateau during the late Cenozoic.
