岩基标点在新沂河海口控制工程沉降观测中的应用

Application on batholith punctuation in settlement observationof Haikou Control Project of Xinyi River

水工建筑物沉降观测需设立观测工作基点,工作基点必须稳定可靠。通过分析新沂河海口控制工程沉降观测成果异常原因,阐述岩基标点建设的缘由、建设过程,分析了岩基标点应用的效果,并就岩基标点可靠性进行了论证。该岩基标点的应用,可为工程监测提供保证,值得在沿海挡潮闸或地基基础较差的工程中推广应用。

The settlement observation of hydraulic structures needs to establish an observation base point,which must be stable and reliable.By analyzing the abnormal causes of settlement observation results in Haikou Control Project of Xinyi River,the reason and construction process of batholith punctuation were described,the application effect was analyzed,and the reliability was demonstrated.The application of the batholith punctuation could provide guarantee for engineering monitoring,which was worth popularizing in the engineering of the coastal tidal barrier or the foundation with poor foundation.
