桩基的历史悠久。浙江河姆渡原始社会居住遗址的临水木柱,就是将柱端栽入淤泥中去的,这就是最早的木桩形式。山西太原晋祠圣母殿,其木桩打入地下水位之下,至今已有九百多年的历史。宋代《营造法式》一书中,还编有“临水筑基”专节,对木桩的应用要求作了明确的规定。随着历史的发展和科学技术的进步,建筑材料的品种增多,施工工艺不断改进,桩基已成为各类建(构)筑物的重要基础形式。桩基础具有承载力高、沉降量小、沉降速度缓慢,既能承受竖向力,又能承受水平力、上拔力、振动力等特点,而且施工简便,可以
The pile foundation has a long history. The Linshui wooden pillars of the primitive social and residential sites in Hemudu, Zhejiang Province, were constructed by putting the end of the column into the silt. This is the earliest form of wooden piles. Shanxi Shengyuan, Taiyuan, Shanxi Province. Its wooden pilings have fallen into the groundwater level. There have been more than 900 years of history. In the Song Dynasty “Creating a French” book, there was also a special section “Lin Shui Jian Zhu Ji”. The requirements for the application of stakes were clearly defined. With the development of history and the progress of science and technology, the variety of building materials has increased and the construction technology has been continuously improved. The pile foundation has become an important basic form of various types of buildings and structures. The pile foundation has the characteristics of high bearing capacity, small settlement, and slow settling speed. It can withstand vertical forces and can withstand horizontal force, pull-out force, vibration force, etc., and the construction is simple.
