黄土地区引调水线路主要工程地质问题及对策

The Main Engineering Geological Problems of Water Diversion Route in Loess Area and Countermeasures

在广泛收集资料及实地调查的基础上,对黄土地区引调水线路工程地质勘察成功经验和失败教训进行总结,详细论述黄土渠道、隧洞、边坡和其他渠系建筑物渠道渗漏、湿陷变形、渠基稳定和黄土高边坡稳定等主要工程地质问题,并对黄土湿陷性处理、边坡防护措施及渠基处理措施进行了探讨。对重新认识黄土地区引调水线路工程地质勘察的主要工程地质问题,指导黄土地区引调水线路工程勘察,统一类似工程勘察工作深度和内容,提高勘察质量及行业规范编制具一定的参考价值。

Based on widely collected data and on-the-spot investigation,the authors summarize the successml experiences and failure lessons on engineering geological investigations of water diversion route in loess region, and expound the main engineering geological problems of the buildings related to canal, such as the loess channel, tunnel, slope and so on, the problems include the leakage of drainage channel, settlement by soaking and deformation, the stability of drainage base, as well as stability of loess slope, in the paper, the authors discuss the treatment for collapsibility loess, protection methods for slope and control measures for drainage base. It has a certain reference value in rediscovering the main engineering geological problems in investigation of water diversion route in loess area, guiding the engineering investigation of water diversion route in loess area, unifying the working depth and content of similar engineering investigations, improving the quality of survey, and framing the industry specifications.
