摘　　要：基于基础地质资料以及3种不同层位岩石的岩土物理学参数,对包括岩溶、红粘土膨胀性等有可能引发地质灾害的因素进行分析。最终认为岩溶在水位变化以及施工荷载的情况下有塌陷的危险,而红粘土的膨胀性会导致地面不均匀沉降,从而引起建筑裂缝。并根据以上地质灾害给出合理的施工建议预防措施。There are a large number of karst landforms in the construction land of walnut industrialization processing plant in Shizong county. Based on basic geology, we have made an analysis of geophysical parameters of the rock in three different horizons. The factors which may lead to geological disasters are also analyzed. At last, it is concluded that the collapse of soil under the condition of water level change and construction load will lead to the collapse of red clay. According to the above geological disasters, the author gives reasonable suggestions for the construction of preventive measures.
