高切坡超前支护桩能有效地抑制边坡的变形,确保开挖边坡的稳定性。但常规钢筋混凝土超前支护桩的刚度大,导致施加在桩体上的土压力较大,为解决这一问题,提出在超前支护桩体靠山侧设置一层EPS垫层材料以降低超前支护桩与变形坡体之间的作用力。采用数值分析方法,研究了EPS垫层材料类型、厚度、刚度对超前支护桩土压力、桩身变形以及桩身内力的影响,揭示了EPS垫层材料对超前支护桩作用机制的影响。研究结果表明:EPS垫层的厚度和密度对超前支护桩桩土共同作用有显著影响。超前支护桩后布置的EPS垫层厚度越大,超前支护桩上的土压力越小,桩身位移越小,桩身内力越小;超前支护桩后布置的EPS垫层密度越小,超前支护桩上的土压力越小,桩身位移越小,桩身内力越小。

Tang ( beijing Synchrotron Radiation Facility, Institute of High Energy Physics, The chinese academy of sciences, beijing 100039, china) ( Laboratori Nazionali di Frascat Inst. of High Energy Phys.

The Si L2,3 X-ray absorption near-edge structure (XANES) can be used to probe thelocal structure around Si and derive electronic information of the unoccupied s- andd-like partial density of states in nano-size SiO2. We present Si L2,3-edge for threedifferent size silicates acquired by total electron yield (TEY) at the photoemission sta-tion of beijing Synchrotron Radiation Facility (BSRF). The Si L2,3-edge spectra areinterpreted based on ab initio full multiple-scattering (MS) calculation. The Si L2.3-edge of nano-size materials has XANES similar to that of a-quartz. The similaritiesbetween the Si L2.3-edge shapes attest to a common molecular-orbital picture of theirSi-O bonding and the same coordination state. However, a considerable broadeningof Si L2,3-edge XANES spectra as decrease of particle size is also an indicative ofpolyhedral distortions.

Based mainly on TOGA-COARE data, that is, the CTD data from R/V Xiangyanghong No. 5 (Pu et al., 1993), the temperature and current data from the Woods Hole mooring and other deep current data, the layered numerical profiles of buoyancy frequency and mean current components are figured out. A numerical method calculating internal wave dispersion relation without background shear current, used by Fliegel and Hunkins (1975), is improved to be fit for the internal wave equation with mean currents and their second derivatives. The dispersion relations and wave functions of the long crested internal wave progressing in any direction can be calculated conveniently by using the improved method. A comparison between the calculated dispersion relation in the paper and the dispersion relation in GM spectral model of ocean internal waves (Garret and Munk, 1972) is performed. It shows that the mean currents are important to the dispersion relation of internal waves in the western equatorial Pacific Ocean and that the currents make the wave progressing co-directional with (against) the currents stretched (shrink). The influence of the mean currents on dispersion relation is much stronger than that of their second derivatives, but that on wave function is less than that of their second derivatives. The influences on wave functions result in the change of vertical wavenumber, that is, making the wave function stretch or shrink. There exists obvious turning depth but no significant critical layer absorption is found.
