首发时间:2014-07-21
摘要:岩石非弹性应变恢复柔量是岩石固有的依赖于时间效应的重要参数,也是非弹性应变恢复法(Anelastic Strain Recovery Method, 简称ASR 法)地应力测量中计算原地应力大小的重要参数。通过实验研究,获得了花岗岩、大理岩和砂岩三种岩石样品的非弹性应变恢复柔量,实验结果表明ASR柔量的大小和变化速率随岩性变化而变化。构建了ASR柔量数值模型,数值模拟结果与实验结果相吻合。

Experimental study of rock anelastic strain rocovery compliances
Abstract:Anelastic strain recovery compliance is the inherent parameter of the rock relying on the time effect, and it is also the important parameter for the anelastics strain recovery (ASR) method to calculate the in-situ stress. The anelastic strain recovery compliances of granite, marble and sandstone are achieved through experimental research. The research results show that the ASR compliances and its change rate change with the lithology. We also propose the ASR compliance numerical model, and the numerical simulation results accord with the experimental results well.
