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。
根據浙江嘉興圍隄工程的原位觀測試驗方案及測試結果,從沉降量、側嚮位移、孔隙水壓等方麵進行瞭分析,錶明未齣現沉降速率連續超標、地基土側嚮位移超標、孔壓增量超控製指標等現象,結果錶明上述數據的大小與地基的土質、加載速率和時間有關。可為工程各部位的具體施工提供參攷,控製好施工過程的加載速率,併通過對後續的沉降量作齣預測,為施工預留超高提供依據。

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 pore-pressure 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 .
