摘要
本文介绍海州露天煤矿非工作帮一次巨大滑坡的整治工程实践,结合岩体的完整程度、滑坡的推力大小、以及软弱岩层等特点,确定以抗滑桩为主,疏干排水措施为辅的综合整治方案,文中论述了以工程造价最低为目标函数,对大型钢筋混凝土抗滑桩的主要设计参数进行优化的方法,由于综合整治,获得了明显的技术和经济效果.
In this paper, a reinforcement engineering of a giant landslide in Haizhou Open Pit Coal Mine is described. Consideing slope integrity, thrust force, and rock strength affected by water content, a combinative support cheme using different kinds of anti-slide poles and draining methods is put forward. Some parameters of armourod concrete anti-slide pole are optimized to minimize the cost of support engineering. A good result is obtained both in technique and economy.
