抗滑桩滑坡治理工程设计.doc

摘要
公路滑坡治理对保护人民的生命财产、保证交通畅通具有重要意义。目前治理公路高陡边坡的措施有SNS柔性防护技术、喷锚网支护技术、抗滑桩墙体系等支挡结构。而抗滑桩工程则由于抗滑桩具有适应性强、特别适用于滑面较深的大型滑坡、对滑坡稳定性和地质环境干扰小、可多桩同时施工、工期较短、抗滑能力强等多方面的突出优点成为滑坡地质灾害治理中一种主要的方法。抗滑桩自60年代在我国铁路部门应用以来,至今已在我国岩土工程与地质工程界普遍采用,并在滑坡治理中起着重要作用。论文较详细地论述了广西南宁至百色二级公路隆安段滑坡处治工程的设计及施工。文中分别介绍了边坡治理工程设计的原则及其治理措施——边坡开挖、边坡加固、边坡排水及边坡环境保护;抗滑桩的施工工艺——成孔步骤、钢筋笼的制做与安装、抗滑桩芯砼浇注等内容。最后,作者做了工程预算,。

Abstract
The prevention of the landslide possesses important significance on safeguarding people’s life and property and guaranteeing the smooth traffic. The measures of ting System,the shotcrete—anchor-mat reinforcement and retaining piles, usually used to remediate the high an dsteep ,the anti-sliding pile has many advantages, such as strong adaptability especially to some big slope with deep sliding surface, less interference to slope stability and geological environments, several piles being constructed at the same time, short construction time and strong resistant sliding ability, it has been a main method to administer geological calamity. Since it was used in railway department in 60's in China, the anti-sliding pile has been widely used in rock and soil engineering and geological engineering field, and plays an important role in those paper introduced the design and construction of the landslide control project on the Road Nanning to Baise in Guangxi province. The designed principle of the slop control project and the control measures——slop mining , slop reinforcement , slop drainage and slop environment protection were supplied. The contructional technology of anti-sliding piles——the process of finishing hole , making and installing steel cages and pouring anti-sliding piles were also introduced. Finally, the designer did budget for this project. The total cost of the project is Yuan RMB.
