在水利水电工程建设中,工程地质勘察是必不可少的重要环节。工程地质勘探、基岩的物理力学性质、工程地质和水文地质条件等等,都是勘察研究的主要内容。特别是,在遇到对工程安全具有危害的产状缓平的软弱岩层和构造复杂的破碎岩石,往往用一般钻探方法无法取得岩芯;靠打平洞、挖竖井或槽探,则时间长,耗费大,还容易发生人身事故,况且由于开挖爆破,破坏了岩体的原来结构,取不到可靠的地质资料,直接影响
In the water conservancy and hydropower project construction, engineering geological prospecting is an essential part. Engineering geological exploration, bedrock physical and mechanical properties, engineering geology and hydrogeological conditions, etc., are the main content of investigation and research. In particular, in the face of soft rock formations and complex fractured rock that are detrimental to the safety of engineering, rock cores are often not obtainable by ordinary drilling methods. By drilling flat holes, digging shafts or flume, the time is long , Is also expensive, but also prone to personal accident, Moreover, as a result of excavation blasting, destroyed the original structure of rock mass, can not get reliable geological data, a direct impact
