深层沉降拟合法计算砂井地基的固结度

Deep Settlement Fitting Process to Compute Consolidation of Sand Drain Foundation

该文采用单向压缩理论,结合当前的砂井地基固结理论,找出加固土体深层沉降与地基附加应力之间的关系。并根据这一规律提出了计算砂井地基固结的深层沉降拟合法。该方法舍弃了繁琐的求解地基附加应力的过程,将已加固完成的、土层性质相类似的地基的深层沉降分布函数代替地基附加应力的分布规律,代入一般的砂井地基的固结方程,就可以求出加固地基固结发展规律,指导工程的进行。

With the present sand drain foundation consolidation theory,this paper uses the one-way compression theory to find out the relationship between deep soil settlement and foundation additional stress,and puts forward the deep settlement fitting process to compute the consolidation of sand drain foundation by this rule.This process forsakes the tediously process of solving the foundation additional stress,takes the deep settlement distribution function of the reinforced and similar soil foundation to replace the distribution rule of foundation additional stress,and substitutes the general consolidation equation of sand drain foundation so as to find out the consolidation development rule of reinforced foundation and guide the implementation of projects.
