摘　　要：在我国,岩土工程领域十分广阔,工程的应力检测、监测显得尤为重要。检测岩土基础的应力变化所用的土压力盒、土压力计种类繁多,有些土压力盒原理相同但结构多样,还有些土压力盒标定方法与实际应用完全不符。基于此,提出一种能够符合现场埋设应用的振弦式土压力盒。该设计是轮辐式工作膜在无盒状态下只接受压力传递片的压力和校准方法。In our country,the field of geotechnical engineering is very broad,engineering stress detection and monitoring is particularly important.There are many kinds of earth pressure boxes and earth pressure gauges used to detect the stress change of rock and soil foundation.Some earth pressure boxes have the same principle but different structure,and some calibration methods of earth pressure boxes are completely inconsistent with practical application.Based on this,a vibrating wire type earth pressure box is proposed,which can meet the field buried application.It is a spoke type working film in the box free state only accept the pressure of the pressure transfer sheet and calibration method.
