中文摘要：

为研究采用嵌入式基础的叠合式地下室外墙板在平面外土侧压力作用下的受力性能,对9个嵌入式基础叠合墙板试件和1个作为对比的现浇混凝土试件进行了静力加载试验,观察两种不同试件的破坏过程和最终的破坏模式,并评估基础嵌入深度、墙板外侧纵筋配筋率、基础外侧杯壁厚度、基础与墙板间接触面是否采用粗糙处理等主要参数对嵌入式基础叠合墙板受力性能的影响。在此基础上,借助有限元分析确定叠合墙板嵌入式基础的计算模型,并给出具体的设计方法,进一步通过理论分析给出基础嵌入深度这一关键几何参数的建议值和取值范围。

英文摘要：

To study the mechanical behavior of superposed exterior basement walls with socket base under lateral earth pressure, nine specimens and one cast-in-place concrete specimen （for comparison） were tested under static lateral load. Damage processes and failure modes of the two different kinds of specimens were observed, and those influences of the factors, including the embedded depth, exterior longitudinal reinforcement ratio of wall panel, thickness of the exterior transverse wall of socket base, and roughness treatment of the contact interface between the base＇ and the wall, etc. , on the mechanical behavior of the superposed wall with socket base were evaluated. Based on the tests and FEM analysis, a calculation model of superposed walls with socket base was developed, and then the corresponding design procedure was proposed. Furthermore, the value range of embedded depth, which is an important geometric parameter, was recommended based on theoretical analysis.
