由于评价土的液化中存在着许多不定因素,因而得不到满意的结果。本文探索了一种新途径,即通过航片判释分析地震液化的宏观机制与震害效应,进而发现地震区的地貌及微地貌特征对于场地液化宏观形迹及地面震害特点有很大影响。利用这种规律,并结合对场地的土质条件进行综合评价,不仅可以较为准确地估计液化的可能性,而且可以从抗震设计观点出发,对地面工程设施的总图布置、规划设计及选择合理的建筑平面形式提供重要依据。本文还从理论上初步探讨了地震液化宏观形迹的形成机制及其不同的破坏作用,以求进一步验证与地面震害的关系,并为这一方法的实际应用提供了基础。
Because there are many uncertainties in the liquefaction of the evaluation soil, satisfactory results cannot be obtained. This paper explores a new way to analyze the macro-mechanism and seismic damage effect of seismic liquefaction through aerial interpretation, and then finds that the geomorphological and micro-geomorphic features of the seismic area have a great influence on the liquefaction macroscopic characteristics of the site and the characteristics of ground seismic damage. Using this law, combined with a comprehensive evaluation of the site’s soil conditions, can not only accurately estimate the possibility of liquefaction, but also from the point of view of seismic design, general layout of the ground engineering facilities, planning and design and reasonable choice The architectural plane form provides an important basis. This paper also theoretically discusses the formation mechanism of macroscopic liquefaction of earthquakes and their different damages, in order to further verify the relationship with ground damage, and provides the basis for the practical application of this method.
