我国幅员辽阔,地大物博,但软土地质在我国也是一种比较常见的地形环境。它们分布在我国沿海地区,然而,沿海地区地形环境对于道路桥梁施工修建有着重要影响。因此,我们就把道桥工程施工修建在软土地基中。在软土地基上修建中,会出现下降或凸起,最主要原因是由于软土地基强度比较低,含水量大以及渗透性差等。这些不利因素对于道桥施工修建有着重要影响,还会对人们生命安全构成一定的威胁。因此,本文对软土地基中道桥工程不均匀沉降的原因作了分析,并提出了防控措施。 Our country is vast in size and vast in area, but soft geology is also a common terrain environment in our country. They are distributed in the coastal areas of our country. However, the terrain environment in coastal areas has an important influence on the construction of road bridges. Therefore, we built the bridge construction in soft soil foundation. In the construction of soft soil, there will be a decline or bulge, the main reason is due to the lower strength of soft soil, water content and permeability and poor. These unfavorable factors have an important impact on the construction of the bridge construction, but also pose a certain threat to people’s life safety. Therefore, this paper analyzes the reasons for the uneven settlement of bridges and bridges in soft soil foundation and puts forward the prevention and control measures.
