基础埋置深度 （embedment depth of foundation ） 一般是指基础底面到室外设计地面的距离，简称基础埋深。对于地下室，当采用箱型基础或筏基时，基础埋置深度自室外地面标高算起。 当采用独立基础或条形基础时，应从室内地面标高算起。
文中还讨论了基础埋置深度对参振土质量和地基刚度的影响。
Meanwhile, the effect of depth of embedded footings on the mass of base soil participating in vibration is also studied.
因此，从基础埋置深度的确定和基础的验算内容两方面分析明挖扩大基础的设计与计算，具有重要的实践意义。
Therefore, it is meaningful in practice that designs and calculates for open-cut foundation from two aspects which are bury length determining and checking computation contents of foundation.
