对济南地区基坑降水引起既有地基沉降的认识
摘要:结合工程经验,对基坑降水引起的周边既有建筑地基沉降的影响因素进行了总结,针对采用分层总和法估算降水引起地基沉降公式中,对应附加应力段的压缩系数取值不准问题,提出了采用基于地层应力历史的降水引起周边地基沉降的估算方法,并结合工程实例对降水引起地基沉降进行了预测。

Abstract:Combined with engineering experience,make a summary to influencing factors about foundation settlement of existing buildings caused by foundation pit dewatering.Aimed at the problem that compressibility in additional stress segment can not be accurately taken in estimating foundation settlement caused by foundation pit dewatering by layer-wise method, propose the method based on formation stress history to estimate foundation settlement caused by foundation pit dewatering,while combining with engineering example,make a prediction for composite foundation settlement caused by foundation pit dewatering.
