平武县农业局良种场边坡治理工程

摘要：在汶川大地震中，平武县是在该地震中受到严重灾害地区之一；在震后建设中，平武县也大力在搞震后整体建设，为搞好震后建设，平武县农业局良种场边坡存在安全隐患，需对该边坡进行治理。

边坡主要有崩塌、滑坡、蠕动变形、座落、岩堆等破坏形式,对于不同的边坡治理应采取不同的计算方法与治理措施。对于边坡治理工程，属于岩土工程之一，所以需要我们进入现场进行工程地质勘察，详细了解场地的岩土工程条件，包括地形地貌、交通环境、地质构造、水文条件等一系列的详细了解。

对边坡进行治理，其主要目的是保持边坡的稳定性，边坡的稳定与否理论上都运用边坡的稳定性系数进行判断。要得到边坡稳定性系数，主要运用土力学，分析边坡的稳定性方法主要有：直线滑动面法，圆弧滑动面法。要保持边坡的稳定性，目前常用的防护措施有：重力式挡土墙，悬臂式挡土墙，桩板式挡土墙，土钉墙，抗滑支挡结构。

在本文中，对平武县农业局良种场作了详细的勘察报告，采用圆弧滑动面法，详细分析了该边坡的稳定性。另外，在设计中，要充分考虑：安全性，经济性，工程环境许可性等原则。出于综合考虑，对平武县农业局良种场边坡的防护措施是采用的重力式挡土墙。

Pingwu County Bureau of agriculture seed field of

slope engineering

Abstract: Wenchuan in the earthquake, Pingwu county is in the earthquake disaster area is one of the serious; after the earthquake in Pingwu County construction, also vigorously to do after the overall construction, do a good job for the reconstruction, Pingwu County Agricultural Bureau seed field slope hidden safety problems, need the slope management.

Major collapse, landslide, slope creep deformation, is located, rock failure form, for different slope management should take the different calculation methods and control measures. To slope engineering, which belongs to one of the geotechnical engineering, so we need to enter the site engineering geological survey, a detailed understanding of field geotechnical engineering conditions, including topography, traffic environment, geological, hydrological condition and a series of detailed understanding.

The slope management, its main purpose is to keep the slope stability, slope stability theory are used to judge the slope stability coefficient. To get the slope stability factor, mainly by the soil mechanics, slope stability analysis methods are: linear sliding surface method, circular sliding surface method. To maintain the stability of the slope, the commonly used protective measures are: gravity retaining wall, the cantilever retaining wall, pile plate retaining wall, soil nailing wall, anti-slide retaining structure.

In this paper, the Pingwu County Agricultural Bureau seed field made a detailed investigation report, with circular sliding surface method, a detailed analysis of the slope stability. In addition, in the design, fully consider: safety, economy, engineering environmental permission principle. Out of consideration, the Pingwu County Agriculture Bureau seed field of slope protection measures are used in gravity retaining wall.

Key words: Pingwu County; slope; management; stability; Investigation
