摘要
本文根据山东厚冲积层条件下不同采深四个开采 3煤地表岩移观测站的实测岩移参数 ,求得了地表岩移参数与采深、冲积层厚度之间的定量关系式。在厚冲积层条件下 ,将冲积层视为随机介质 ,基岩看成粘弹性基础上的粘弹性梁 ,建立了地表沉陷与变形预计计算公式 。
Based on practical observing strata parameter of four surface strata observation stations in condition of thick alluvial soil in Shandong three collieries in this paper, the quantity relationship formulas are obtained. In condition of mining under thick alluvial soil, the alluvial soil regarded as random medium and the bedrock upon as viscoelaticity foundation, the calculation equations were set up for predicting and calculating surface subsidence and deformations. It is well with the actual situation.
