摘要
针对微型组合桩在公路滑坡抢险工程中的应用,以四川省达州市宣汉县S202 公路边坡堆积体微型桩治理工程为案例,开展倾斜式微型组合桩工程实践应用研究,通过数值模拟对比竖直桩(实际方案)和三斜桩(推荐方案)的边坡防护效果和经济效益.可知两种微型桩布置方式均能满足滑坡抢险处理需求,布置竖直桩时,边坡稳定性系数为 1.61;布置倾斜桩时,边坡稳定性系数为1.96,较布置竖直桩时稳定系数提高了近13.6%,节约成本近40.7%,三斜桩抗滑效果更优.
Abstract
For micro combination piles in highway engineering,the application of landslide disaster in Sichuan Dazhou S202 Xuanhan county highway slope deposit micro pile treatment project as a case,tilting the micro pile engineering practice the application study,nu-merical simulation(actual)and three vertical pile inclined pile(recommended)slope protection effect and economic benefit.The results show that the two kinds of micro-pile arrangement can meet the needs of landslide emergency treatment.When vertical piles are ar-ranged,the slope stability coefficient is 1.61.The slope stability coefficient is 1.96 when inclined piles are arranged,which is nearly 13.6%higher than that when vertical piles are arranged,and the cost saving is nearly 40.7%.The anti-sliding effect of tri-inclined piles is better.
