深层土体水平位移监测及影响因素浅析

基坑监测包括基坑支护结构应力及变位监测、周围建筑物沉降及地下水位观测、土体分层竖向位移监测、深层土体水平位移监测等等。本文结合工程实践,以泉州中芸洲海景花园城基坑工程项目深层土体水平位移监测为例,介绍处于复杂地质条件下的基坑深层土体水平位移监测成功经验,针对基坑深层土体水平位移监测进行分析总结,鉴于前人经验理论,总结深层水平位移曲线图的变化与支护结构类型等有关,特别与支撑点的设置有一定的关系,深层水平位移在有支撑点处的位移一般较没有支撑点处位移发展的慢,到后期深层水平位移曲线图会发展成"弓型"或"括弧型";在监测的过程中要结合现场实际情况来判断监测数据是否存在失真的可能性以及保证监测数据的准确性的措施等相关结论。

Horizontal displacement of depths soil monitoring and Analysis of factors affecting

Monitoring of excavation, including bracing and retaining structural stress and deformation monitoring of groundwater levels around the building settlement and observation, monitoring of soil layering vertical displacement, horizontal movement of depths soil monitoring and so on. This combination of engineering practice, Zhong Yun Zhou in Quanzhou City, Seaview Garden excavation project to monitor the horizontal move- ment of depths soil as an example, Introduced in complex geological conditions of horizontal movement of depths soil monitoring of success experi- ence, according to horizontal movement of depths soil monitoring are analyzed and summarized, in view of previous experience theory, Summary of horizontal movement of depths soil curve changes with the retaining type of bracing and retaining structure and so on, especially with the bracing of the set have a certain relationship, The horizontal movement of depths soil in the points of bracing movement is generally no points of bracing move- ment development slow, Later the horizontal movement of depths soil curve will develop into a ＂ bow＂ or＇i bracket type＂; In monitoring process should be based on the actual situation to judge whether there is the possibility of monitoring data distortion and to ensure the accuracy of monitoring data the measures and other relevant conclusion.
