基坑测试在深基坑支护中的应用及实例分析

Foundation pit testing application in the deep foundation pit supporting and case analysis

介绍了基坑测试的仪器和功能,结合具体工程实例,探讨了基坑测试在深基坑支护工程中的应用,阐述了土压力盒、钢筋计、锚杆拉力计的安装方法,并跟踪测试土压力、挡土桩内力、锚杆拉力等随施工的变化过程,为类似地质条件的深基坑支护设计和施工提供了理论依据。

The instrument and function of foundation fit testing were introduced.Incorporated with specific engineering example,the foundation fit testing application in the deep foundation pit supporting was discussed.The adjusting methods of soil pressure cell,reinforcement mere,anchor pull tension gauge were illustrated and traced testing of earth pressure,retaining pile and anchor pressure change with construction progress,which can provide theoretical basis for the similar engineering.
