【摘要】 巷道围岩松动圈支护理论是20世纪70年代末产生的一种软岩巷道支护理论,此后不断发展完善,形成了以围岩分类、支护理论、测试技术、支护设计与施工相结合的一整套支护理论体系,实践支护效果显著,应用广泛。本文主要介绍了巷道松动圈支护理论的基本内容,阐述了几种常用围岩松动圈测试技术的基本原理,并结合工程实例,介绍了地质雷达在测试围岩松动圈中的应用,取得了较好的测试效果,具有一定的推广意义和应用价值。更多还原

【Abstract】 Roadway surrounding rock loose circle supporting theory,a kind of supporting theory for soft rock strata,was recommended in the late 1970s.This theory has been developed into a complete set of supporting theory system,including rock classification,supporting design,testing technology,and construction methods.Supporting results are obvious in practices and widely used.The basic content of loose circle supporting theory was introduced and several foundation principles about testing technology were presented.Combined with engineering practice,GPR application in testing surrounding rock loose circle was introduced and a good result was obtained.All the work above has a certain meaning and application value.更多还原
