摘要
地震作用是产生震陷的主要动荷因素 ;多种自然、人为因素引起的温室效应会造成地下水位上升 ,而地下水位上升又会对震陷产生较大的影响。在给出地震作用下考虑地下水位上升而影响震陷的简化分析方法的同时 ,指出了地下水位上升对震陷量影响的规律。
Seismic settlement, which has disastrous influences on the stability of infrastructures, has a close relation with the underground water table. The global warming, caused by the human induced greenhouse, will result in the rising of the water table of sea, river and groundwater. Based on the test results of soft clay and sand and the layerwise summation methods, a simplified procedure is presented to evaluate the seismic settlement in consideration of the effect of the groundwater table rising. Detailed analysis of the variation of seismic settlement due to groundwater table rise is given as examples.
