摘要
根据浙江嘉兴围堤工程的原位观测试验方案及测试结果,从沉降量、侧向位移、孔隙水压等方面进行了分析,表明未出现沉降速率连续超标、地基土侧向位移超标、孔压增量超控制指标等现象,结果表明上述数据的大小与地基的土质、加载速率和时间有关.可为工程各部位的具体施工提供参考,控制好施工过程的加载速率,并通过对后续的沉降量作出预测,为施工预留超高提供依据.
The in-situ observation program and test results of the cofferdam project in Jiaxing are analyzed in this paper,in the perspectives of settlement,lateral displacement,pore pressure,etc.,which is related to the foundation soil,loading rate and duration. The results reveals there is no phenomenon relevant to sedimentation rate,lateral displacement and porepressure increment,providing a reference for the specific construction of various parts. It is also suggested that,by keeping proper loading rate on construction,the prediction of the subsequent settlement should be made to provide reference for the reserved ultrahigh construction.
