序言CFG短桩复合地基技术是我们依据北方地区建筑地质状况,针对普通CFG桩(简称:长桩)施工中存在的不足,而提出的全新的地基加固理论。1998年12月申报了发明专利,2002年8月国家专利局授予了发明专利权,专利证号:98 1 25248.6。经过多年的施工实践,CFG短桩复合地基技术推广应用取得了长足的进展,取得了良好的经济、技术和社会效益,现作以下总结。
Preface CFG short-pile composite foundation technology is a new theory of foundation reinforcement based on the construction geological conditions in the northern part of our country and aiming at the shortcomings in the construction of ordinary CFG piles (referred to as long piles). In December 1998, the invention patent was declared. In August 2002, the State Patent Office granted the invention patent with the patent number of 981 25248.6. After years of construction practice, great progress has been made in popularizing and applying CFG short pile composite foundation technology, and good economic, technical and social benefits have been achieved. The following summarizes the results.
