砂井堆载预压固结软土地基五十年代已在我国推广,随着对“砂井”、“堆载”、“预压”及“排水”各工序的改进,此法应用更为广泛。七十年代浙江大学曾国熙教授来厦门市讲学,推荐了此法,并对我们的试验进行全面性的指导,为特区建设作出贡献。“预压”发展到“自压”是利用建筑物本身的重量,分级逐渐加荷施压,当地基在一级荷载作用下固结后,再施加下一级荷 Sand well pile preloaded consolidated soft soil foundation has been promoted in China in the fiftieties, with the processes of “shaft”, “overload”, “preloading” and “drainage” For improvement, this method is more widely used. In the 1970s, Professor Zeng Guoxi of Zhejiang University came to Xiamen and gave a lecture. He recommended this method, provided comprehensive guidance for our experiments, and made contributions to the construction of the Special Zone. “Preloading” developed to “Self-pressured” is the use of the weight of the building itself, gradually increasing the pressure applied by the classification, after the local foundation is consolidated under the primary load, the next primary load is applied.
