摘要

本文详细介绍了德化酒店边坡的工程概况、场地工程地质条件、岩土体的物理力学性质及其稳定性的分析和支护方案的设计。该边坡为分为四段，总长为130米，高6.0-20.2米，为了保证边坡的稳定性,根据酒店边坡设计基本要求和设计参数等多种因素，通过对边坡特征结合地质分析和计算，对边坡的稳定性进行了定性分析和定量计算。在对该边坡进行稳定性分析的定量计算中，采用了理正软件对边坡进行了计算及模拟分析，并得出了最不稳定的滑动面。分析及计算表明，该边坡不符合稳定性要求，需要进行支护。根据边坡概况及场地条件整个边坡，该边坡的第一、第二段支护方案采用了喷射砼面板，该边坡的第三、第四段的支护方案采用了锚杆格构梁支护，并对其锚杆的锚固力、锚固角进行了计算，并通过计算和对比选取了锚固长度，最后通过锚杆锚固力确定了格构类型。本边坡支护设计方案在满足边坡稳定性的情况下兼顾降低工程造价以及支护工程施工的可行和方便。

Abstract

This paper introduces in detail the Dehua hotel slope engineering,engineering geological conditions, rock and soil physical and mechanical properties and stability analysis and the design of the supporting scheme. The slope is divided into four sections, the total length of 130 meters, 6.0-20.2 meters high, in order to ensure the stability of the slope, according to the basic requirements of the hotel slope design and design parameters and other factors, the slope characteristics combined with the geological analysis and calculation, the slope stability of qualitative analysis and quantitative calculation. In the quantitative stability analysis of the slope calculation, using the calculation and simulation analysis of slope software, and the sliding surface is the most unstable. Analysis and calculation shows that, the slope does not meet the stability requirements, the need for support. According to the site conditions of the slope and the slope, the slope of the first, second supporting scheme by using the spraying concrete panel, third, fourth section of the slope supporting schemes using anchor lattice beam support, and the anchoring force, anchorage angle were calculated, and the selection of anchorage length through calculation and comparison, the anchoring force to determine the lattice type. The slope support design to meet the slope stability under the condition of both lower the project cost and supporting construction is feasible and convenient.
