| 1 | Influence of groundwater drawdown on excavation responses e A case history in Bukit Timah granitic residual soils显示文摘Performances of a braced cut-and-cover excavation system for mass rapid transit(MRT) stations of the Downtown Line Stage 2 in Singapore are presented. The excavation was carried out in the Bukit Timah granitic(BTG) residual soils and characterized by significant groundwater drawdown, due to dewatering work in complex site conditions, insufficient effective waterproof measures and more permeable soils. A two-dimensional numerical model was developed for back analysis of retaining wall movement and ground surface settlement. Comparisons of these measured excavation responses with the calculated performances were carried out, upon which the numerical simulation procedures were calibrated. In addition, the influences of groundwater drawdown on the wall deflection and ground surface settlement were numerically investigated and summarized. The performances were also compared with some commonly used empirical charts, and the results indicated that these charts are less applicable for cases with significant groundwater drawdowns. It is expected that these general behaviors will provide useful references and insights for future projects involving excavation in BTG residual soils under significant groundwater drawdowns. | Wengang Zhang Wei Wang Dong Zhou Runhong Zhang A.T.C.

| 5 | 根据表面线荷载预测混凝土挡墙的土压力显示文摘本文研究了表面线荷载对混凝土悬臂挡墙顶部产生的侧向压力。因为混凝土悬臂挡墙结构的设计受到作用于挡墙顶部产生的侧向土压力的极大影响,这种侧向压力是很重要的。用有限元法进行了深入的研究,分阶段模拟了挡墙的施工和填筑。土质用一种完全弹塑性结构关系来模拟,而混凝土—土体接触面上的界面构件用一种双曲线结构关系来模拟。用有限元法预测的侧向压力与基于弹性理论的传统方法预测的侧向压力不同,这种差异被认为是由于弹性理论中的错误推论造成,而弹性理论中任何一种有效的主应力关系的结合对回填土是合理的。 | A.T.C.戈霍 孙增生 | 1995 | 路基工程1995，，4： | 0 |
