摘 要

本文介绍了乌兰木伦镇金龙路某住宅楼东侧边坡支护设计工程。根据鄂尔多斯伊旗乌兰木伦镇金龙路某住宅楼东侧边坡支护设计工程详细勘察报告，拟建场地位于伊金霍洛旗乌兰木伦镇西段，东临越山西路，西临矿业西路，南临乌兰木伦大街。本厂区土层除地表人工填土外，其下主要为第四纪以及侏罗系基岩为主，第四系覆盖层厚度在18.0m左右。整体周边环境稍复杂且对边坡稳定性影响较大。在设计过程中查阅了有关边坡支护的设计及治理资料，并且结合乌兰木伦镇金龙路某住宅楼东侧边坡的详细勘察资料，最终选定圆弧滑动法来验算边坡稳定性，本设计计算只采用了南京库仑公司GEO5岩土软件电算的方式。

从各个方面考虑确定边坡支护方案，例如工程的经济性、安全性、施工便利等因素以及场地工程地质、水文地质条件及边坡高度的不同，将其他段分作3个剖面端（1-1’剖面段、2-2’剖面段、3-3’剖面），采用放坡 格构梁 锚杆（索）支护、 放坡 土钉支护、 毛石混凝土挡墙 放坡 土钉支护设计方案。本课题验算过程中涉及瑞典条分法、材料力学、钢结构等相关理论。

The design of the east side slope of a residential building in Jinlong road, Wulanmulun town

Abstract

This paper introduces the east side slope support design of a residential building on Jinlong Road, Wulanmulun town. According to the Erdosyiqi, Jinlong Road, Wulanmulun town a residential building on the eastern side of the slope support engineering design detailed survey report,the proposed site is located in the west section of Wulanmulun Town, Yijinhuoluo, on the East, Shanxi Road, West Mining Road, and Wulanmulun street in the South. In addition to surface artificial fill, the soil layer in this plant is mainly Quaternary and Jurassic bedrock, and the thickness of Quaternary covering is about 18.0m. The surrounding environment is a little complicated and has a great influence on the slope stability. In the design process of access on the slope supporting design and management of data, and combining with the survey data in the town of Wulanmulun, Jinlong Road, a residential building on the eastern side of the slope, the final selection of Fellenius to calculate the slope stability calculation using Coulomb Nanjing geotechnical software company GEO5 computer and hand in two ways of the design.

Various aspects are considered to determine the slope supporting scheme, such as the economic, safety and construction convenience of the project, as well as the differences of site engineering geology, hydrogeological condition and slope height,the other sections will be divided into 3 section ends (1-1 'profile section, 2-2 'profile section, 3-3 'profile section),the sloping and lattice beam anchor (cable) support, sloping and soil nailing, rubble concrete retaining wall, slope and soil nailing design. In the course of checking, the paper involves the Fellenius , the material mechanics, the steel structure and so on

Key words: Stability; Slope support; Anchor cable
