某场地高边坡和洪水综合治理工程研究
摘要:某项目场地选址于两侧南北走向山脊间的深切“V”字形沟谷中，南、北、东三侧面临突出的岩土问题，即南、北两侧高边坡稳定和东侧山谷洪水治理。三侧岩土问题在时空上呈耦联、递进关系，治理难度较大，在系统阐述三侧岩土问题工程地质特征的基础上制定了防护治理对策。研究及实践表明，精确的工程地质资料是岩土治理的基础，而对治理工程全局概念性的把控又是指导勘察设计的关键，治理设计与治理勘察紧密结合是岩土治理工程的核心要素；选址于山谷的工程防洪是关键问题，需建立通畅的排洪渠道，依据场地重要性等级科学合理制定防洪标准，确定频遇流量；对于小型滑坡治理，优先采取清方处理措施更为合理，对于清方后的耸立的高边坡需进行稳定性分析、评价，确定合理的防护对策，确保整个边坡的安全。
Abstract:A site is located in the deep V-shaped valley between the north-south ridges on both sides. It faces stability of high slopes on both sides of the south and north and flood control in the east valley. The geotechnical problems on the three sides are coupled and progressive in time and space, and there are considerable difficulties in treatment. Based on the systematic description of the engineering geological characteristics of the geotechnical problems on the three sides, the protection and treatment countermeasures are formulated. The research and practice show that the accurate engineering geological data is the foundation and premise of geotechnical treatment, and the overall conceptual control of the treatment project is the key to guiding the investigation and design. The close combination of treatment design and treatment investigation is the core element of the success or failure of geotechnical treatment engineering. Flood control of the project located in the valley is a key issue and it is necessary to establish a smooth flood discharge channel, scientifically and reasonably formulate flood control standards according to the importance level of the site, and determine the frequent flow. For the treatment of small-scale landslide, it is more reasonable to give priority to the treatment measures of clearing the earth. For the high slope after clearing the earth, it is still necessary to carry out stability analysis and evaluation, determine reasonable protection measures, and ensure the safety of the whole slope. The contents can provide guidance and reference for similar projects.
