| 摘 要： | 现代建筑工程中高层、超高层建筑基础大部分采用桩基础。对于灰岩地区，由于工程地质条件较差，存在大量的土洞、软土层、溶洞、节理、裂隙等不良地质现象，往往极大地影响着桩基础的设计与施工。广核大厦采用高压旋喷复合地基加筏型基础。实践表明，广核大厦地基处理技术，解决了在岩溶地区挖孔桩、灌注桩、钻（冲）孔桩难于成桩且工期无法保证的技术难题，地基处理效果显著，克服了灰岩地区各种不良地质现象的影响，增加了基础施工的安全性。

| Abstract: | Based types of high-rise and super high-rise architecture in modern building engineering are mostly pile foundation. Because of the complicated geological condition in linestone area and the bad geological phenomenon such as cave,soil cave,soft soil ,joint,fissure and so on.Usually design and construction of pile based greatly.Guang he building is used high pressure ratating and ietting compound ground and raft based.The practice shows:Guang he building foundation treatment technology solved the hard techno... |
