根据笔者近年来在鲜水河断裂带考察所取得到的一些实际资料,从该区几次强震所造成的地震地裂缝特征,并以道孚松林口为界,鲜水河断裂带北西、南东两段的地貌特征,初步分析了该断裂带所处的构造应力状态。一、鲜水河断裂带及其地貌表现 (1)鲜水河断裂带的展布鲜水河断裂带北西起自甘孜东谷附近,向南东经炉霍、道孚、乾宁至康定以南,呈北西向直线状断续延伸,长达300余公里(图1)由
According to some actual data obtained by the author in the investigation of the Xianshuihe fault zone in recent years, from the characteristics of the earthquake ground fissures caused by several strong earthquakes in the area and bordered by the Daofu Songlingkou, the Xianshuihe fault zone is northwest, South and East of the two sections of the geomorphological features of the tectonic tectonic stress state. 1. Xianshuihe Fault Zone and Its Geomorphic Features (1) Distribution of Xianshuihe Fault Zone The Xianshuihe fault zone starts from the vicinity of the east valley of Ganzi and runs eastward through Luhuo, Daofu and Ganning to the south of Kangding , Extending linearly northwest to the intermittent extension of up to 300 km (Figure 1) from
