拱形抗滑支挡结构应用研究

针对边坡与滑坡治理工程中广泛应用的悬臂式抗滑桩、锚索抗滑桩存在的问题，提出了一种新型抗滑支挡结构即拱形抗滑支挡结构，从理论的角度研究了该种结构治理滑坡的抗滑机理，并将此结构与悬臂式抗滑桩及锚索抗滑桩从内力及工程量上进行了对比分析，得出该结构治理滑坡具有造价低、能利用拱效应发挥混凝土抗压性能等优点，相对传统抗滑结构具有一定的优越性。

Study on Application of Arch Anti-Sliding Retaining Structure

In connection to the issues existing in cantilever and anchor anti-sliding piles used extensively in slope and landslide treatment project，a kind of new arch anti-sliding retaining structure is proposed.The paper explored the anti-sliding mechanism of this structure in landslide treatment theoretically and，comparing to cantilever and anchor anti-sliding piles，analyzed the inner force and engineering quantity respectively.As a result，the conclusion that comparing to traditional anti sliding structures，this structure has the characteristics of low cost and being capable of giving full play of compressive property of concrete under arch effect leading to a relative advantage is obtained.
