针对沐若电站厂区存在边坡强风化层厚、岩性较差、地下水丰富等不利地质条件。在开挖支护设计过程中,根据施工期和运行期的不同特点和要求,将初期支护与后期加固相结合,采取了挂网锚喷支护、锚筋桩、格构梁和边坡排水系统等措施。基于现场勘查和地质资料以及安全监测资料分析成果,及时修改和调整了边坡加固设计,保证了边坡稳定。工程实践表明,所采取的加固和排水措施技术可靠、经济合理。
For Mu Ruo power plant there is strong slope thick weathering layer, poor lithology, groundwater rich and other adverse geological conditions. In the process of excavation and support design, according to the different characteristics and requirements of construction period and operation period, the initial support and post-reinforcement are combined, and the anchoring and bolting support, anchorage pile, lattice beam and edge Slope drainage system and other measures. Based on the site survey and geological data as well as the analysis results of safety monitoring data, the slope reinforcement design was revised and adjusted in time to ensure the slope stability. Engineering practice shows that the reinforcement and drainage measures adopted are reliable and economical.
