摘要
通过对珠江三角洲地区活动断裂、砂土液化、软土震陷、塌陷地震、滑坡、崩塌和孤立地形和不均匀地基等场地震害分析,预测了珠江三角洲地区未来场地震害的主要形式是砂土液化和软土震陷,同时不可忽视其他震害的影响。利用砂土、软粘土层大量吸收地震能量来防止强震中建筑物的倒塌和破坏将成为场地震害分析的一个新趋势。
The analysis was done about site earthquake damages in the Pearl River Delta area, such as active rift, sand liquefaction, soft soil earthquake sinking, karst collapse earthquake, landslide, dilapidation and island terrain. The result showed that sand liquefaction and soft soil earthquake sinking would be the main site earthquake damages in this area in the future, and the effect of other site earthquake damages could not be neglected in the meantime. It would be a new tendency that how sand and soft clay largely absorb seismic energy in order to prevent building collapse in a strong shock.
