粱沟村大型单体危岩治理设计

危岩的治理方法有主动加固、被动防护、定向爆破等，这些方法或多或少地存在着治理费用高、施工强度大、破坏当地原始生态环境等缺点。为避开这些缺点，针对粱沟村后山危岩体所处的实际地质环境条件及危岩体自身特征，考虑岩体抗拉强度小的特点，运用力矩平衡原理，采用类似于伐木的方式，巧妙地清除粱沟村危岩体。通过简易的工程措施，减少了工程费用，达到了减灾防灾的目的。

Design on Treatment of Large Single Dangerous Rock at Lianggou Village

Treatment of dangerous rock includes active reinforcement，passive protection and directional blasting，in respect of which shortcomings of high cost，intensified construction and damage to local original ecological environment somewhat exist.Therefore，considering the actual geological conditions of the dangerous rock on the mountain behind Lianggou Village and the own features of the rock and including the rock’s small tensile strength and the rationale of moment-equilibrium，the dangerous rock at Lianggou Village is eliminated cleverly in a way similar to woodcutting.Through simple engineering measures，project cost is reduced and disaster reduction and prevention reached.
