摘要:

提出了一种可在岩土体表面直接测量弹性参数的方法,并且研制了其配套装置; 叙述了该方法的具体实施步骤和装置零部件的连接关系,并对该方法的理论依据做了简要的推导; 最后利用商用数值模拟软件PLAXIS 3D Tunnel验证了该方法的实用性和理论的正确性。结果表明:岩土体弹性参数表面测试方法和装置可直接利用隧道掌子面或基坑侧壁进行弹性参数测试,从而避免从地面打孔的繁琐工序。

Abstract:

A test method of elastic parameters on surface of rock and soil was proposed, and its supporting device was developed. The specific implementation steps of the method and the connectivity of device components were described, and the theoretical basis of the method was derived. Finally, the practicability and correctness of the method were verified by using commercial numerical simulation software PLAXIS 3D Tunnel. Results show that test method of elastic parameters on surface of rock and soil and its supporting device can be directly used for tunnel face or pit wall elastic parameters of the test, and the tedious process from the ground punch can be avoided.
