三次样条插值曲线在Asaoka法中的应用
摘要:在软土地基上修筑高等级公路,能否确保工程按期保质完成,关键之一在于能否正确估算地基沉降量。利用已有的沉降观测资料来预测未来的沉降,Asaoka方法就是较早提出的一种,它不仅简单易用而且有一定的理论基础,使得该方法与目前国内常用的经验曲线配合法有着本质的区别,这也是它今天能够吸引众多学者研究的原因。对Asaoka从理论基础和沉降递推结果进行了分析,利用三次样条插值曲线来处理非等时间间隔的沉降观测资料,结果表明,这种处理方法是可行的。
Abstract:Whether the engineering quality of the highway constructed on the soft soil foundation can be guaranteed mainly lies in the correct prediction of settlement of raft ground foundation. Asaoka's method is an early method using observational settle ment to predict further settlement, it is simple and based on theory, so Asaoka's method is essentially different from other methods. This is the reason why.so many scholars study on it. This article analyzes the basic theory and deduces the results of settlement, and make use of the cubic spline interpoliation to deal with the observational settlement of not uniform interval, the results indicate that this method is feasible.
