摘　　要：公路桥梁的不均匀沉降会造成巨大的损失。为解决相应难题,利用理论公式进行了沉降计算,并运用塑料排水板对道路桥梁地基进行加固,对工程进行了地基孔隙水压力及沉降监测,同时根据具体施工给出了相应的控制措施。结果显示,该实验工后沉降较小且不均匀沉降符合工程需要。The uneven settlement of highway bridges will cause huge losses. In order to solve the corresponding problems,this paper uses the theoretical formula to calculate the settlement,and uses the plastic drainage board to reinforce the road and bridge foundation. The foundation pore water pressure and settlement of the project are monitored,and the corresponding control is given according to the specific construction measures. The results show that the experimental results show that the settlement is small and the uneven settlement meets the engineering needs.
