摘　　要：某工程场地地质勘探结果为无地下水 ,在基坑开挖和基础施工时也未见地下水 ,而在基础施工完成、基坑回填 1个月后 ,出现基础隆起、地下室底梁及顶板顶梁多处开裂的事故。采用现场测试和有限元计算对此进行了分析研究 ,研究结果表明 ,该事故是由于雨水渗入基坑造成的。在研究基础上 ,提出了一个简单经济的地基加固处理方法。该工程经验可供设计类似场地上建筑物时参考。No ground water was discovered during pit excavation and foundation construction for a certain project,but one month later,after finished the foundation construction and filled the foundation pit,it was discovered that the beam and slab of foundation were cracked and ridged.This paper analyses it by using FEM calculation and field research.It was discovered that it was caused by rain water which dipped into the pit.Based on the analysis,this paper presents a simple treatment method.The experience can be used as reference for similar buildings.
