支撑盲沟与抗滑桩联合治理富水滑坡实例分析
|
摘要
对于浅层富水性滑坡的有效治理,疏干、引排滑坡体内的地下水十分关键。探究治理浅层富水滑坡可行有效、造价节约的工程治理联合措施,以期为类似滑坡治理工程实践提供参考。结合曹家咀滑坡治理工程实例,讨论支撑盲沟的相关设计问题(适用条件、布置位置及间距、结构形式及断面尺寸等);提出"支撑盲沟+抗滑桩"联合措施设计计算方法、设计流程;比较联合措施与抗滑桩单一支挡措施,前者有利于减小抗滑桩桩身截面强度。采用"支撑盲沟+抗滑桩"联合措施治理浅层富水滑坡可兼顾"抗滑与治水"的治理目标,技术可行、造价节约、施工快捷,滑坡支挡和坡体地下水的疏干、引排效果明显。
For effective control of shallow Water-saturated landslide, dewatering and drainage of groundwater in landslide are very important. To explore the feasible, effective and cost saving joint measures for the treatment of shallow water-rich landslides, in order to provide reference for similar landslide management engineering practices. The relevant design problems of supporting blind ditch(applicable conditions, layout location and spacing, structure form and section size, etc.) are discussed in the light of the example of cao-jiazui landslide management project. The calculation method and design flow of the joint measure of "supporting blind ditch+stabilizing piles" are put forward. Comparing the joint measures with the single block measures of anti-skid pile, the former is beneficial to reduce the strength of the body section of anti-skid pile. The joint measures of "supporting blind ditch+stabilizing piles" can be used to treat shallow water-rich landslides. It can take into account the management goals of "anti-skid and water-control", which is technically feasible, economical in cost, and fast in construction. The dry and drainage effects of landslide support and slope groundwater are obvious.
