Study of Deformation Monitoring and Destruction Mechanism of Preventing Wall of Engineering Center

Preventing wall ofengineering center was destroyed due to uncertainly of geology condition.The article analyzes its destruction mechanism and discusses a better method of deformation monitoring from the view of secutity, it includes the arraneg ment of surveiyng and base point, the layout of surreying point, observation scheme, monitoring procision and the error of measurement.Then it analyzes security of this project by practical results of observation.
