摘要
自1976年大地震以来,岩溶地面塌陷已成为唐山市重要的地质灾害类型而引起有关方面的关注。本文系统地介绍了八五期间完成的唐山市岩溶塌陷模型试验研究成果,首先,通过对唐山市岩溶塌陷发育的环境条件的剖析,建立了塌陷发育的地质模型,然后,详细叙述了不同地质模型的试验结果,给出了它们的临界条件,并对不同模式塌陷的综合防治方法进行了讨论。
Since the earthquake happened in 1976, karst collapse has become a new geohazard in Tangshan and has got more attention. During the period of the Eighth Five Years Projects, a large scale model experiment of karst collapses in Tangshan had been performed. In this paper, through the analysis of environmental condition, the geological models of collapse is set up. And then, corresponding to these models, the results of experiment are discussed in detail, and it is given the critical condition to collapses. Finally,the counter-measure regulations to different collapses are given.
