双曲线法、指数曲线法和Asaoka法在汕揭高速公路的对比分析
摘要:预测路基沉降是软土地区高速公路建设需要解决的重要问题。结合汕揭高速公路路基沉降实测数据，对双曲线法、指数曲线法、Asaoka法等常见的沉降预测方法在软土地区的精准度进行研究。结果表明，双曲线法及Asaoka法拟合曲线与实测数据较为吻合，适用于汕揭高速公路的沉降预测。同时分别对影响双曲线预测法和Asaoka预测法准确度的主要因素进行了分析，明确如何提高其预测精准度。
Abstract:Estimation of the settlement in subgrade is one of the most critical problems in expressway. By the settlement measured data of shan-jie expressway, the paper research the common method in the estimation of settlement, such as hyperbola model exponential curve model and Asaoka model. The results show that hyperbola model and Asaoka model are more consistent with the measured data,applicable estimation of the settlement in shanjie expressway. The main factors which affect the accuracy of hyperbola model and Asaoka model were analyzed. How to improve its predictive accuracy was clear.
