介绍了某小区二期地下室基坑及边坡设计,该工程周边地形复杂、高差变化较大,为5.8~12.35m,且与周边已建建筑物距离较近,基坑开挖对土体位移的控制要求有所差别,结合周边情况的不同分别采用了自然放坡、钻孔灌注桩排桩加支撑、土钉墙、复合锚杆挡墙,重力式挡墙等不同的支护形式,以确保基坑施工及周边建筑物的安全,结合信息化施工达到了较为理想的效果。
The design of the basement and slope of the second basement of a residential district is introduced. The surrounding terrain of the project is complex and the elevation difference varies a lot, ranging from 5.8 to 12.35m. The excavation of the foundation Displacement control requirements are different, combined with the surrounding situation were used in different natural grading, cast-in-place bored piles plus support, soil nailing wall, composite anchor retaining wall, gravity retaining wall and other forms of support, In order to ensure the safety of the foundation pit construction and the surrounding buildings and achieve the ideal result with the information construction.
