成都粘土广泛分布于成都平原三级阶地上,裂隙极为发育。以往多从满足一般工程的需要出发,笼统地将其视为一种均质连续体,且仅限于一般工程地质性质的研究。对于它所具有的重要地质特征——裂隙性,虽认识到它的存在及其在土体稳定中所起的重要作用,但从未做过专门工作,针对这一情况,本文在野外调查的基础上,选取代表性地点,观察、取样,通过大量的实验资料,就裂隙性对成都粘土力学性能的控制作用进行了多方面的探讨。 Chengdu clay is widely distributed on the third terrace of Chengdu Plain, and the fracture is extremely developed. In the past, most of them met the needs of general engineering and generally considered it as a homogeneous continuum, and were limited to the study of general engineering geology. For its important geological feature, fissure, it recognizes its existence and its important role in soil stability, but it has never done any special work. In view of this situation, this article has been investigated in the wild. Based on the above, representative sites were selected, observed and sampled, and a large number of experimental data were used to explore the control effects of fissures on the mechanical properties of Chengdu clay.
