摘要
为研究木桩在中国古代建筑中的作用,借助考古与文献资料,对城墙、桥梁、佛塔、宫殿等基础下的木桩进行了探讨。木桩多为垂直的,其功能在于直接传递建筑荷载到下面坚硬的岩层上,或者利用木桩本身的桩尖阻力,以提高基础的承载力,减少沉降。木桩亦有横铺的,称之为睡木,或木筏,主要是为了加强基础的整体性。实践表明,古人所用的木桩,达到了建筑对基础坚固性的要求。现代高层建筑地基中的水泥柱桩与钢筋网的加固技术,与古代的木桩、睡木相似。
By means of archaeological and documentary materials,this article discusses the timber piles under foundations of city walls,bridges,pagodas,palaces and so on in order to study the effect of ancient buildings.Most timber piles are vertical,directly passing on the building load to the hard rock below or using the wood pile tip resistance in order to improve the load-bearing capacity of foundation and to reduce settlement.Some are horizontal,called sleeping wood or raft foundation,mainly strengthen foundation entirety.Practice shows these timber piles can meet the requirements of a solid foundation of buildings.Reinforcement technology of concrete column and steel net in the understructure of modern high rise buildings is similar with ancient timber piles and sleeping wood.
