摘　　要：本论文分析了现行地壳形变观测方法中存在的弊端,给出了一体化观测改进方案。具体方法是将现行的水管倾斜仪、洞体应变仪的分离式布设结构改为由两仪器组合而成的三角形结构面,通过对两套仪器三分量的一体化观测,可获取观测面受大地形变所产生的地倾斜和应变物理量,有效提高地壳形变观测的预报效能。This paper analyzes the drawbacks of current crustal deformation observation methods and pro-vides an integrated observation improvement plan. The specific method is to change the separated layout structure of the current water pipe tiltmeters and cave strain gauges to a triangular structural plane formed by the combination of two instruments. Through the integrated observa-tion of the three components of the two sets of instruments, the ground tilt and strain physical quantities generated by the large terrain deformation on the observation surface can be obtained, effectively improving the prediction efficiency of crustal deformation.
