Study on Comprehensive Treatment of Geotechnical Engineering in a Site Area

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.
