［摘要］重庆某连续斜坡上带核心筒的框架-剪力墙掉层结构，由于无明显接地端，造成基础嵌固设计存在较大的不确定性。在强调概念设计的基础上，将此结构的基础嵌固问题转换为结构核心筒剪力墙的基础嵌固问题，进一步提出核心筒部分的“挖填找平”嵌固解决方案，即通过开挖边坡“挖平”、设置箱形基础“填平”，最终形成具有统一标高的核心筒基础嵌固端，使核心筒基础由无明确接地端转变为明确的上、下接地端，从而解决结构的基础嵌固问题。在确保边坡稳定的前提下，并对结构采取一系列加强措施后，经多遇地震弹性分析及罕遇地震下静力弹塑性分析，认为该基础嵌固解决方案行之有效。

Abstract:There is a comparatively large uncertainty in the foundation-fixed design of the frame-shear wall structure with corewall supported by foundations with different elevations on a continuous slope in Chongqing because of lack of indistinct embedding end. On the basis of emphasizing conceptual design, the foundation-fixed problem of this structure was transformed into the foundation-fixed problem of the corewall shear wall of the structure, and the embedment solution of "excavation, filling and leveling" for the corewall part was further proposed. The corewall foundation embedment end with uniform elevation was finally formed through the excavation of the slope and setting of the box foundation for filling. The corewall foundation was changed from no explicit embedding end to clear upper and lower embedding ends, thereby solving the problem of structural foundation-fixed. On the premise of ensuring the stability of the slope, and after taking a series of strengthening measures for the structure, based on the elasticity analysis under frequent earthquakes and static elastoplasticity analysis under rare earthquakes, the foundation-fixed solution was considered to be effective.
