摘要
地下硐室巷道工程在爆破开挖过程中围岩会产生松动,利用超声波探测技术并结合现场地质条件可以较准确地测出巷道围岩松动圈的范围,从而给巷道围岩支护提供可靠的依据,是一种成功的方法。
The underground chamber and tunnel engineering can produce to loose in the course of blasting and excavation. By using the technology of supersonic test and combining with the spot geology condition, the scope of the tunnel wall rocks loose zone can quite accurately measure out, thereby offering a dependable basis to the support of tunnel wall rocks. It is a kind of successful method.
