贵州省黔东南天柱县坪地镇某滑坡治理工程设计

摘  要

本文基于贵州省黔东南天柱县坪地镇某滑坡治理工程的实际需求，针对该滑坡因持续强降雨导致的稳定性和安全性问题，进行了详细的工程地质条件分析、滑坡稳定性计算以及治理工程方案设计。首先，通过收集和分析现场岩土勘察资料，明确了滑坡的成因、规模及危害程度。随后，运用Bishop条分法对滑坡的稳定性进行了理论计算和软件分析，确定了滑坡的稳定性状态及剩余下滑力。在此基础上，结合库伦土压力理论，设计了包括抗滑桩、格构锚杆、截排水系统等在内的综合治理方案，并通过对比不同治理措施的经济性和可行性，最终确定了最优治理方案。

设计过程中，详细阐述了抗滑桩的设计原理、计算方法及施工组织设计，包括抗滑桩的布设、内力和变形计算等关键步骤。同时，为了确保治理效果，还设计了滑坡治理工程的监测方案，包括施工期安全监测和防治效果运营期长期监测。此外，针对滑坡区域的生态恢复，提出了相应的排水与绿化工程设计。

本文的研究成果不仅为坪地镇某滑坡的治理提供了科学依据和实用方案，也为类似滑坡灾害的治理提供了参考和借鉴，具有重要的理论价值和实践意义。

Design of a landslide control project in Pingdi Town, Tianzhu County, Qiandongnan County, Guizhou Province

Abstract

Based on the actual demand of a landslide treatment project in Pingdi Town, Tianzhu County, Qiandongnan County, Guizhou Province, this paper analyzes the landslide stability calculation and addresses the stability and safety problems caused by the continuous heavy rainfall. Firstly, by collecting and analyzing the site geotechnical survey data, the cause, scale and harm degree of the landslide are clarified. Then, we made the theoretical calculation and software analysis of the stability of landslide by using Bishop section method, and determined the stability state and residual sliding force of landslide. On this basis, combined with the theory of Cullen soil pressure, the comprehensive treatment scheme including anti-slip pile, lattice bolt, intercepting and drainage system is designed, etc., and the optimal treatment scheme is finally determined by comparing the economy and feasibility of different treatment measures.

In the design process, the design principle, calculation method and construction organization design of the anti-skid pile are expounded in detail, including the key steps of its layout and internal force and deformation calculation. At the same time, in order to ensure the treatment effect, the monitoring scheme of the landslide treatment project is also designed, including the safety monitoring during the construction period and the long-term monitoring of the prevention effect during the operation period. In addition, for the ecological restoration of the landslide area, the corresponding drainage and greening engineering design is proposed.

The research results of this paper not only provide a scientific basis and practical scheme for the treatment of a landslide in Pingdi Town, but also provide a reference for the management of similar landslide disasters, which has important theoretical value and practical significance.

Key words: landslide control; stability analysis; Bishop classification method; anti-skid pile design and monitoring scheme
