摘要
本文针对云南天生桥电站的粗粒料(简称 A 料)进行了系统的各向等压湿化及剪切湿化试验研究。研究表明:湿化条件下的应力应变、变形参数及强度特性不能简单地用饱和态所代替,湿化与饱和态之间存在一个临界压力。提出了湿化变形计算的归一化公式及其参数。同时对湿化特性的影响因素做了不同程度的探讨,取得了一些有益的结论。
Systematic Wetting tests are made of one coarse material,Taking from Tianshengiao station under isotropic compression and shearing condition(σ_3 =c).The results show that the stress strain relationships,the deformation parameters and the stangth characterics con not be simply replcaed by those of a saturated state,A critical pressure,between wetting state and the satu- rated state is found.A wetting model is put forword and its computational parameters are determined.We investigate the main influence on the wetting and its progress,As a result some useful conelustion are drawn.
