城市给水管道的施工场地狭窄，其沟槽开挖施工受多种因素的影响，容易产生边坡失稳问题。在对给水管道工程的施工技术分析的基础上，通过建立物理模型分析了不同密实度、含水率条件下不同状态土质边坡的稳定性，测试结果表明不同状态的土体边坡稳定性会随着压实程度而提高，边坡土体的含水率应控制在最佳含水率范围内，土质边坡在降雨时应采取防护措施防止其被雨水侵蚀。% The urban water supply pipeline construction site is narrow, and the groove excavation construction is influenced by many factors, so it is prone to appear the slope instability problem. Based on the analysis of water supply pipeline engineering construction technology, through establishing physical model to analyze the different soil slope stability with different compactness and moisture content, the test results show that different status of soil slope stability will be improved with the compaction degree, and the moisture content of soil slope should be controlled within the scope of the optimum moisture content, and the soil slope should be taken protective measures to prevent the erosion by rain.
