摘　　要：随着社会发展,城市复杂环境中的深基坑工程越来越多,以济南市某深基坑工程为例,介绍了在城市复杂环境中上部放坡+下部桩锚以及复合土钉墙相结合的支护设计方案,使支护结构具有针对性和适用性,基坑监测数据表明以上支护形式合理有效,能够保证基坑边坡及周边环境的安全稳定,可为类似工程提供一定的参考。With the development of the society,more and more deep foundation pits were excavated in urban complex environment,taking a deep foundation pit in Ji’nan as an example,a support design plan combined with slop and pile anchor and composite soil nailing wall was introduced,and the plan becomes more pertinent and adaptable.The foundation pit monitoring data show that the support design plan is reasonable and effective,and it can ensure the safety of pit retaining wall and environment,thus it can provide a reference for similar projects.
