市政工程建设除了具有施工对象是固定的,施工场所是移动的,以及一次性修建,露天作业等一般建筑工程的特性外,还有它自己的更为独特的特点。首先,它的广延性较建筑工程要大。一条道路,一条管道,穿沟过河绵延数公里,因此它与环境发生的矛盾要比一般建筑工程大的多。例如折迁配合问题,从开工到完工都可能遇到,成为创造施工条件,保证工程进展的第一个大问题。其次,它的被动性工作(工序)较一般建筑工程要多。所谓被动性工作是指取决于 The construction of a municipal project has its own unique characteristics in addition to the fixed construction object, the construction site being mobile, and the characteristics of general construction projects such as one-time construction and open-air operations. First of all, its extensiveness is greater than that of construction projects. A road, a pipeline, and ditching across the river stretches for several kilometers, so the contradiction between it and the environment is much greater than that of general construction projects. For example, the problem of relocation and coordination may be met from the start of construction to the completion of the project, becoming the first major problem in creating construction conditions and ensuring the progress of the project. Second, it has more reactive work (processes) than general construction projects. The so-called passive work means that
