摘要:
选取工程中遇到的典型地层作为实验土样,在12%~32%含水率条件下分别进行侧限压缩试验,得到不同含水率条件下的原状土固结时的应力-应变曲线;借助Origin数据分析软件,使用数据拟合方式建立了可描述全风化花岗岩非线性压密过程的数学模型,定量研究了全风化花岗岩在常规注浆压力(0~4MPa)下的压密特性。
Abstract:
Typical strata encountered in the project were selected as experimental soil samples, and lateral confined compression tests were conducted under conditions of 12% to 32% water content to obtain stress-strain curves for undisturbed soil consolidation under different water content conditions. With the help of the Origin data analysis software, a mathematical model was established using data fitting to describe the nonlinear compaction process of fully weathered granite, and the compression characteristics of fully weathered granite under conventional grouting pressure (0-4 MPa) were quantitatively studied.
