摘要
以天水市秦州区白家堡子滑坡为研究对象,利用已有资料和野外实地勘察对其发育特征和物质组成进行系统的分析。明确了白家堡子滑坡属牵引式中厚层黄土—泥岩滑坡,滑体主要组成物质是黄土及部分全—强风化泥岩堆积层,滑体分上下两层滑面,滑面位于黄土—泥岩交界面或泥岩中,滑体缺少约束条件,较易变形失稳,长期处于活动状态。最后,根据白家堡子滑坡的特征,结合该区域的城市详细建设规划,初步提出白家堡子滑坡治理措施,为后期相邻滑坡的治理提供参考。
Taking the Baijiapuzi landslide in Qinzhou District of Tianshui City as the research object,the development characteristics and material composition of the landslide are systematically analyzed using existing data and field investigations.The investigation found that the Baijiapuzi landslide is a towed medium-thick loessmudstone landslide.The main components of the landslide are loess and some weathered mudstone deposits.The sliding body has two upper and lower sliding surfaces.The sliding surface is located at the interface of loess and mudstone or in mudstone,which is easy to deform and lose stability,and it is active for a long time.According to the development characteristics of the landslide,combined with the detailed urban planning of the region,the treatment measures for the Baijiapuzi landslide are initially proposed,which provides a reference for the treatment of adjacent landslides in the later period.
