摘要
结合地勘报告对光电研发基地工程地质情况进行分析,明确了工程的特点和难点,经过对多种基坑支护方案进行比较,合理选用了对浅埋软土边坡采用风化砂和石渣换填结合锚杆、土钉支护体系进行基坑边坡处理的施工方案,并对该方案进行了理论分析及设计,给出了具体的施工工艺。通过工后监测,该施工技术对处理软土基坑的边坡效果良好。
Combined with geological exploration report analysis to the engineering geology condition of photoelectric rd base,authors clear the characteristics and difficulties of project.Through comparing with a variety of foundation excavation supporting schemes,authors make a reasonable choice of construction scheme that filling weathered sand to the soft soil slope and combining ballast aggregate changing with anchor,soil nailing support system for excavation slope processing,and the scheme is analyzed theoretically and designed,finally,the concrete construction technology is got.After monitoring by work,the construction technology for the treatment of soft soil foundation excavation slope has obtained good effect.
