摘要:
本文依托某挡土墙加固工程,结合实施环境、项目实施工期、安全、经济、技术等因素对加固方案进行了综合比选,选用扰动小的拼接螺旋钢桩进行地基加固处理,选择轻型悬臂式挡土墙结构方案,采用自钻锚杆将既有浆砌片石挡土墙与悬臂式挡土墙进行连接,打通泄水孔,加强现场监测,最终确定合理的路基结构形式。本研究为类似挡墙加固工程提供了借鉴案例。
Abstract:
Based on this retaining wall reinforcement project,combined with the implementation environment,project implementation period,safety,economy,technology and other factors,this paper makes a comprehensive comparison and selection of reinforcement schemes,selects spliced spiral steel piles with little disturbance for foundation reinforcement,selects the light cantilever retaining wall structure scheme,uses self-drilling anchor rods to connect the existing mortar rubble retaining wall with the cantilever retaining wall,opens drainage holes,strengthens on-site monitoring,and finally determines a reasonable subgrade structure form. It provides a reference case for similar retaining wall reinforcement projects.
