复杂环境下的市政定额工程路基开挖方式选择

Selection of Embankment Excavation Method for Municipal Quota Project in Complex Environment

市政工程施工环境复杂,石方开挖风险系数相对较高,同时与清单计价相比,定额计价中采取不同的施工方式也对项目成本及效益有更大的影响。在施工中选择合理的施工方式既确保施工安全,又可在不影响项目的施工成本和进度前提下,最大化施工方的利益。以贵州双龙航空港经济区二堡路道路建设工程为例,分析复杂环境下的市政定额工程路基开挖方式如何选择,才能在保证施工安全及进度的前提下,最大化施工方的利益,包括分包商。

The construction environment of municipal engineering is complicated and the risk factor of rock excavation is relatively high.At the same time,compared with list pricing,different construction methods in quota pricing also have a greater impact on project cost and benefit.Choosing a reasonable construction method in construction not only ensures construction safety,but also maximizes the benefits of the constructor without affecting the construction cost and schedule of the project.Taking Erbao Road Construction Project as an example,this paper analyses how to choose the excavation method of subgrade for municipal quota project in complex environment so as to maximize the benefit of the constructor on the premise of ensuring construction safety and progress.
