基础是建筑物必不可少的主要组成部分,工业与民用建筑中基础型式大多采用天然地基上建立独立或条形基础,这类基础土方量大,耗用工料多,工期长,若在冬期负温下施工,施工难度更大,冬施费用高,质量不易保证,故过去基础工程都尽量在冬前或初冬期施工完毕,回填复盖过冬,只有少量
The foundation is an essential part of the building. Most of the basic types of industrial and civil buildings are built on natural foundations to establish an independent or strip foundation.
