| 摘 要： | 在二维剖面上，抗滑桩两侧岩土体规模及形态差异导致桩两侧静止侧压力的合力不等，且合力作用点也不在同一水平线上，这直接影响作用于抗滑桩上的弯矩与剪力。滑体在重力作用下存在整体滑动及侧向膨胀两种效应：当滑动面倾角较小时，侧向膨胀效应占优势，抗滑桩的设计荷载应依据桩两侧静止侧压力合力之差；当滑动面倾角较大时，滑动效应占主导地位，抗滑桩的设计荷载可根据各种条分法来确定。此外，通过有限单元法算例说明数值计算方法是求解静止侧压力的有效工具。

| Abstract: | In two-dimensional profile,the resultant of the static lateral pressure on both sides of anti-slide piles are not equivalent and not in the same horizontal line because of the difference of scale and shape of slope, which will directly affect the flexural torque and shear of resistant pile. There are two effects of whole sliding and laterally swelling for the gliding mass under the action of gravity.When the dipping angle of the slide surface is slow, the lateral swelling will be predominant, which implies that load designing should depend on the difference of resultant of static lateral pressure on both sides of anti-sliding pile; When the dipping angle of the slide surface is steep, the whole sliding will be predominant, which implies that load design could be determined by classical slice methods. Furthermore, it is shown that numerical simulation is a powerful tool to calculate static lateral pressure with a case study by the finite element method. |
