摘　　要：岩石的溶蚀对岩溶的产生至关重要,溶蚀机理及其影响因素的研究对于溶蚀现象解释必不可少。针对研究较少的钙质砂(砾)岩,采用试验模拟的方法,考虑了影响岩溶发育的影响因素去研究钙质砂(砾)岩的溶蚀特点。研究认为:钙质砂(砾)岩溶蚀速度缓慢;岩石样品的固有特性对岩溶发育有重要影响;岩样的状态因素不是溶蚀的控制性因素,钙质砂(砾)岩的溶蚀速率慢于同等条件下的碳酸盐岩。The corrosion plays an important role on karst formation. The mechanism of corrosion and its influence factors must be taken into account when explaining the effects of the karst. According to the cal-gritstone or cal-conglomerate with few information,the purpose of present work is to study the characteristic of corrosion considering its influence factors. The result shows that the rate of corrosion is very slow,the intrinsic characteristics have much effect on the development of the karst and the form of the sample is not the decisive factor and the velocity is slower than carbonate rocks.
