摘　　要：针对目前地基规范中尚无水库浸没区建筑物地基承载力计算的内容,通过分析水库浸没对建筑物地基的影响机理,并对浸没建筑物地基土体的物理力学特性开展试验研究,建立了水库浸没区建筑物地基弹塑体结构的计算模型。通过图示给出水库浸没区浅埋基础安全深度的求解方法,为水库浸没区建筑物处理区域范围划定提供参考。The hearing capacity of building＇ s foundation in reservoir immersion area is not covered yet in the existing foundation standards.The influence of reservoir immersion on building foundation was analyzed,and the physical and mechanical properties of foundation soil of submerged buildings were studied through tests.On this basis,the calculation model of elastic-plastic body of foundation building in reservoir immersion area was established,and the graphical solutions for the safe depth of building foundation was proposed.This research is a reference for the determination of building treatment scope in reservoir immersion area.
