摘要
拟建的500 kV变电站工程地区地势相对较起伏。对拟建地块地基土构成与特征、地下水、土腐蚀性特征、不良地质作用进行详细分析,进而对膨胀土、基础方案、人工边坡稳定进行分析与评价。场地适宜工程建设,(3)号、(4)号土层可作为良好的天然地基持力层,(4)号土层可作为桩端持力层。挖方边坡可主要考虑自然放坡的形式;填方边坡在坡高低于11 m时,采用自然放坡的形式。研究结果为后续工程建设提供可靠的参考数据。
The proposed 500 kV substation project area is relatively undulating. In this paper,the composition and characteristics of the foundation soil,groundwater,soil corrosive characteristics and adverse geological effects of the proposed plot are analyzed in detail,and then the expansive soil,foundation scheme and artificial slope stability are analyzed and evaluated. It shows that the site is suitable for project construction,No. 3 and No. 4 soil layer can be used as a good natural foundation bearing layer. The No. 4 soil layer can be used as the pile end bearing layer. It can mainly be considered to use the form of natural grading in the excavation side slope. When the filling slope is lower than 11 m,the type of natural grading can be uesed. The research results provide reliable reference data for subsequent engineering construction.
