摘要
通过对浅层强风化炭质页(灰)岩进行深入的勘察检测和分析,将原设计的冲(钻)孔灌注桩优化为筏形基础,介绍了浅层地基土承载力取值、筏形基础浅埋稳定性分析、基础沉降预测等关键问题和沉降实测数据反演结果,对软硬不均地基上的筏形基础提出采用统计方法预测沉降的思路。
After detailed geo-tech investigation,site test and data assessments for strong weathered rock stratum,the foundation of two blocks of high-rise residential buildings are optimized from bored piles to raft on strong weathered rock.Some critical technical challenges and their practical solutions are demonstrated and discussed,such as evaluation of bearing stratum capacity,stability of raft with insufficient embedded depth required by the codes of practice,as well as settlement estimation.Records of settlement survey are presented,together with feedback analysis based on survey data.The statistic method to site investigation data is recommended for future settlement estimation.
