摘要

土压力是基坑支护结构上的主要水平荷载形式。实际工程中由于土压力的大小受各种因素的影响而与理论值相差悬殊，在基坑支护设计时土压力的取值直接与支护结构未来的安全稳定性相关。通过对润扬长江公路大桥北锚碇深基坑工程土压力监测资料进行分析，得出坑壁土压力随开挖进行具有不同的分布形式，这对同类工程可靠性设计以及研究土-结构相互作用机制均具有重要意义。

Abstract

Earth pressure is the main load on the retaining structure of foundation pit. The really earth pressure is very different from that of theoretic one due to many factors. The reliability of earth pressure controls their safety and stability in support structure designing. By analyzing the monitoring data of earth pressure on the diaphragm wall

which using as retaining structure for deep foundation pit of north anchor for Run-Yang Bridge

it is found that the earth pressure diagram is different in every excavation stage

that is

it changes with excavation and supporting. This will be very important to reliability design for resemblance engineerings. Moreover

it will be a base for soil and structure interaction study.
