摘要
本文通过理论分析和加固实例,证明了目前预压加固中常用的实测沉降过程线推算固结参数的方法,用沉降比S_t/S_∞等同于孔压消散比(u_0—u_t)/u_0表示固结度是偏于不安全的。文章还介绍了新的计算方法。
Based on the theoretical analysis and practical example of consolidation work, this paper gives demonstration that the conventional method of calcu lating the consolidation coefficient by actual observed settlement(by preloading) line, ie, assuming the settlement ratio St/Soo to be equivalent to the pore pressure dissipation ratio(u0-ut)/u0 in expressing the degree of consolidation, will lead the way to an unsafe side. A new calcalation method is suggested in this paper.
