| 摘 要： | 随着各地治理“马路拉链”工程及明挖施工对城市交通的影响,以暗挖等非开挖方式穿越道路的工程越来越多,随之对道路安全运营也带来了潜在风险。提出施工前应对道路承载变形的能力进行分析预判,总结了地下穿越工程对道路影响分析的重点、难点和分析的主要内容、流程及方法。期望对类似项目有借鉴意义。

| Abstract: | Along with the"road zipper"projects governed in various regions,and the influence of excavation construction on urban traffic,there are more and more the crossing-road projects by underground excavation and trenchless modes,which brings potential risks to the safe operation of road.This paper puts forward that the capacity of road bearing deformation should be analyzed and predicted before construction,summarizes the emphases and difficulties of influence analysis on underground crossing project on road,and analyzes the main contents,technological processes and methods,which is expected to be useful for the similar projects. |
