基坑变形监测及其数据处理方案(2)

Abtract

This design is mainly for a deep foundation pit during the construction of foundation pit deformation and cause the deformation of the surrounding environment monitoring methods and data processing program design and analysis.The main monitoring content of the foundation pit wall for monitoring horizontal displacement and settlement monitoring;In support of lattice column for subsidence monitoring; near an excavation foundation pit surrounding by effect of buildings for subsidence monitoring;The surrounding building settlement of super early warning value requirements of the tilt observation.The monitoring method for precision two level, the polar coordinate method, points method,And its feasibility was made precision analysis.

Keyword: Horizontal displacement observation; settlement observation; tilt observation; two level; polar coordinates
