摘　　要：在软土地基上修建公路、城市道路,如何控制路基的沉降、沉降速率和工后沉降量是影响路面质量、行车安全、使用寿命等的关键性问题;而如何通过现有的实测沉降资料来准确计算和预测工后沉降是我们现在亟待解决的问题.结合东莞西部干道软土路基沉降实测资料采用不同分析方法运用沉降曲线拟合进行工后沉降量推算,从而得到适用软土路基工后沉降的实用分析方法.Concerning building a city road on the soft soil foundation, how to control the settlement of the road soil ground, the settlement velocity and the settlement after construction has become the key engineering problem of affecting the road surface quality, riding security, sevice life and so on . However, how to calculate and predicat the last settlement quantity through present actual settlement data is an urgent problem. This paper uses the soft soil foundation actual settlement data of west road of Dongguan city to recken the last settlement quantity and find the best calculating methods of the similar engineering from the comparison between reckening process and reckening results.
