Construction and design method of newly-built foundation pit support structure adjacent to existing foundation pit
The invention discloses a construction and design method of a newly-built foundation pit support structure adjacent to an existing foundation pit. According to the newly-built foundation pit support structure, a support pile adjacent to an excavated foundation pit is used as a part of a newly-built foundation pit support pile; the fender posts are used as a retaining structure of an excavated foundation pit (1) and a retaining structure of a newly-built foundation pit (4); the fender posts are connected with the enclosure structure of the newly-built foundation pit through inner supports; the fender posts are connected with structural columns of an excavated foundation pit through supporting oblique beams. The invention provides a design and calculation method for the axial force of a shared fender post inclined support. According to the construction method, fender posts close to an excavated foundation pit serve as fender posts of a newly-built foundation pit, and the shared fender posts (2) are connected with a newly-built foundation pit enclosure system through horizontal supports (3) and connected with structural columns of the excavated foundation pit through supporting oblique beams. The method has the characteristics of cost saving, convenience in construction and contribution to safety and stability of the foundation pit.
一种紧邻既有基坑的新建基坑围护结构的施工及设计方法，所述新建基坑围护结构利用紧邻已开挖完成基坑的围护桩作为新建基坑围护桩的一部分；所述围护桩作为已开挖基坑（1）的围护结构，也作为新建基坑（4）的围护结构；所述围护桩与新建基坑的围护结构通过内支撑连接；所述围护桩与已开挖完成的基坑的结构柱通过支撑斜梁连接。本发明提供了共用围护桩斜支撑轴力的设计计算方法。本发明施工方法将临近已开挖完成基坑的围护桩作为新建基坑的围护桩，该共用围护桩（2）与新建基坑围护体系通过水平支撑（3）相连接，与已开挖基坑的结构柱通过支撑斜梁相连接。本发明具有节约成本，方便施工，有利于基坑安全稳定的特点。
