Determination of disturbance effect by sonic wave velocity to underground engineering blasting on wall rock of tunnel in Xiaolangdi water conservancy project 小浪底水利枢纽地下工程爆破对隧洞围岩扰动影响的声波检测
Application of Cross-hole Sonic in Integrity Detection of Underground Diaphragm Wall 声波透射法在地下连续墙完整性检测中的应用
Application of Sonic method in determining surrounding rock loosening belt of underground cave 声波法在测定地下洞室围岩松弛带中的应用
Measuring results of sonic velocities of rock samples subjected to shock produced by underground nuclear explosion are given in this Paper. 本文给出了地下核爆炸爆后围岩样品声速测量结果。
Practice had demonstrated that quick survey of loosening belt of underground cave surrounding rock by sonic method is an indispensable site monitoring measure for promoting NATM-construction in excavation of underground caves. 实践证明,声波法快速测定地下洞室围岩松弛带,是地下洞室开挖推广新奥法施工不可缺少的现场监测手段。
