摘　　要：随着长江经济带发展战略全面实施和生态文明建设加快推进,实现完成黑臭水体治理目标,市政管网工程建设占据着越来越重要的地位,控制工程投资是市政管网工程的重要因素。以浏阳市某河流域排水片区雨污分流工程为研究对象,在保证项目质量达标与施工安全前提下,根据沟槽放坡开挖、板式支护开挖、槽钢支护开挖和钢板桩支护开挖等施工工艺,比较同一开挖深度下不同支护方式对应的沟槽开挖工程造价,分析各种支护方式的经济合理性,结果表明市政道路下沟槽开挖选用支护方式更为经济,可为业内市政管网工程造价控制及投资决策提供借鉴。With the implementation of the development strategy of the Yangtze River Economic Belt and the acceleration of the ecological civilization construction,and the realization of the goal of controlling black and odorous water bodies,the construction works of municipal pipe network occupies an increasingly important position.Controlling project investment is an important aspect of municipal pipe network projects.Taking the diversion works of rain and sewage water in a drainage area of a river basin in Liuyang City as the study object,under the premise of ensuring the works quality and construction safety,based on various support methods at the same excavation depth such as the trench grading excavation,slab support excavation,channel steel support excavation and steel sheet pile support excavation,the paper compares and analyzes the economic rationality of various support methods.The results show that trench excavation support under municipal roads is more economical,and the study can provide reference for cost control and investment decision-making of municipal pipe network engineering.
