We must deal with the crude soft soil artificially in order to meet the demand of groundsill intension, distortion and anti-seismic etc.
为了满足地基的强度、变形和抗震等要求，必须对天然的软弱土地基进行人工处理。

Underground structures, being confined by the surrounding rock or soil, have long been assumed to have good anti-seismic ability.
地下结构由于受到周围岩体或土体的约束，一直被认为具有良好的抗震性能。
