【摘要】浙江建设科技研发中心项目,其施工场地狭小,基坑周边环境复
杂,深基坑土方开挖施工网难。通过在第1道内支撑上设置栈桥作为施工道路, 解决了土方开挖的交通运输问题。同时采取分区块进行土方开挖,降低了施工难度,加快了施工进度,在基坑施工过程中实现全方位的基坑监测,保证了在复杂环境条件下深基坑的施工安全。为以后类似深基坑土方开挖施工提供依据。

(Zhejiang Dacheng Construction Group ., Hangzhou 310012,China) Abstract: The difficulty of Zhejiang construction technology R&D center
project,is the Narrow construction site and plex surrounding environment of foundation pit, resulting in some problems about excavation of deep foundation pit.
By setting the trestle bridge as the construction road in the first passage,we can
solve the transportation problem of the earthwork excavation. At the same time, we
may take the partition block for earth excavation,which can reduce the construction
difficulty,speed up the construction progress and implement a full range of
foundation pit monitoring in the process of foundation pit construction,ensuring the
construction safety of deep foundation pit in plex environment conditions. This
paper provides the basis for later similar earthwork excavation of deep foundation
pit construction.
Key words: deep foundation pit; complex environment; earthwork excavation;
monitoring
