为克服狭小场地条件下地下连续墙钢筋笼施工困难的问题，提出一种新型地下连续墙配筋形式，并将其命名为“桩式墙”。首先，通过公式推导对桩式墙进行设计；
然后，对其施工过程进行数值模拟，并将数值模拟结果与监测结果进行对比分析；最后，形成桩式墙结构的设计方法，并以抗弯性能为切入点对比桩式墙结构、传统地下连续墙结构及支护桩结构的优缺点。研究结果表明：
与传统地下连续墙结构相比，同等情况下应用桩式墙结构需使用1.27~1.58倍的纵向钢筋，但可使施工期间的灵活性大幅提升，可在狭小或复杂场地深基坑围护结构设计与施工中应用。
To realize reinforcing cage construction of
underground diaphragm in narrow and complex construction site, a new type of
underground diaphragm wall reinforcement is put forward, which is named as pilewall.
In this paper, the formula of the pilewall design
method is deduced, the construction process is simulated and compared with the
monitoring results. Finally, the design method of pilewall
structure is formed, and the advantages and disadvantages of piletype wall structure, traditional underground diaphragm structure,
and shelter pile structure are comparatively analyzed in terms of bending
capacity. The results show that compared with the traditional underground
diaphragm structure, the pilewall structure needs
1.27~1.58 times of steel bars, which ensures a significant improvement in
flexibility during construction and provides guidance and reference for the
design and construction of deep foundation pit retaining structure in narrow or
complex sites.
