【摘要】 土压力准确计算是基坑工程设计的关键。为切实提高土压力计算的准确性,进行了大量的基坑周边土压力现场监测,以现场监测数据为依据,总结出了华北平原地下不同深度土压力(水平主应力)计算的统计型经验公式和基坑开挖导致的坑壁土体水平主应力损失的统计型经验公式,介绍了土压力现场监测方法与过程,给出了监测实例。更多还原

【Abstract】 Accurate calculation of soil pressures of pit walls is the key to the design of foundation pit engineering.To improve the accuracy of soil pressure calculation,field observations of soil pressures of pit walls were performed.Based on the observed data,a statistical empirical formula was put forward of for soil pressures and main horizontal stress losses of pit walls in foundation pit excavation in north China plain.The field observation ways,process,and examples were introduced.更多还原
