中文摘要:结合上海四平大楼加层工作，根据该建筑物初建时与加层时的两次勘探资料，从工程地质角度，对加层中的砂土液化以及加层引起的建筑物附加变形问题进行了分析探讨。分析结果表明，软土地区建筑物本身荷载的长期作用，对于改善与提高地基土强度以及砂性土层的抗液化性能是非常有益的。

Analysis on Engineering Geological Problems Related to Storey-addition of Siping-Building in Shanghai
Abstract:Based on the in-situ investigation results for the storey-addition of Siping-Building, the engineering geological problems relate liquefaction of sandy soils and the settlements of an existed building caused by the storey-addition activities have been discussed. Results show that the long-time load of buildings is very useful for the increasing of both the strength of sub-soils and the anti-seism ability of sandy sub-soils.
