( 8 ) for the sake of overcoming the shortage of the former work , axisymetrical analytical solutions of vacuum combined surcharge preloading were deduced , the effect of surcharge loading speed was considered and vacuum was regard as instantaneous load , so we can take account of effect of surcharge loading time , well resistance and smear , it is more closed to practical engineering
( 8 )根据以前真空-堆载联合预压解析解的不足之处，推导了真空-堆载联合预压下地基孔压及固结度的解析解。本文的解析解将真空荷载视为瞬时施加，而将堆载荷载的施加考虑为线性施加过程，因此可以考虑堆载施加的时间影响，与实际工程情况更摘要加接近，并可同时考虑井阻、涂抹的影响。
