随着沿海大中城市的相继开放,在百万平方公里的软土地基上大兴土木,以及随之带来的交通事业的蓬勃发展,近年来钻孔灌注桩基础工程有了迅猛的发展。山东北镇黄河大桥采用钻孔灌注桩基础,桩长达104M之深,已达到国际先进水平。上海市许多高层建筑,重型厂房,立交车行与人行桥和其它市政工程中,都在陆续采用钻孔灌注桩型式作为基础工程,这是大趋势。一、回顾与展望回顾钻孔桩在上海地区发展的一段历程。在五十年代末、六十年代初上海也曾行了一阵子。但在市区重要工程上,一直
With the successive opening up of large and medium-sized coastal cities, the massive expansion of civil engineering on one million square kilometers of soft soil foundation and the consequent rapid development of transportation, the foundation engineering of bored pile has undergone rapid development in recent years. Shandong Huanghe Yellow River Bridge using bored pile foundation, pile up to 104M in depth, has reached the international advanced level. Many high-rise buildings in Shanghai, heavy-duty factories, interchanges and pedestrian bridges and other municipal projects, are gradually using the bored pile type as a basic project, which is the general trend. I. Review and Prospect Review the history of the development of bored piles in Shanghai. In the late fifties and early sixties, Shanghai also had a long walk. However, important projects in urban areas, has been
