| 摘 要： | 从堆载预压和真空预压固结过程的不同，推导获得了堆载预压、真空预压和真空联合堆载预压条件下土体强度的增长公式，并与规范公式进行了分析比较。结果表明：真空预压和堆载预压引起的土体强度的增长并不相同，堆载预压引起土体强度增长值较规范公式略小，真空预压引起土体强度增长值较规范公式略大。因此建议对按规范公式计算获得的土体强度增长值进行适当调整。

| Abstract: | Solutions to soil strength growth resulted from different preloading methods are obtained respectively according to different consolidation process, and then the solutions are compared with standard formulae. The results show that soil strength growth attained from vacuum preloading is different from that obtained from surcharge preloading, and soil strength growth ac- quired from the proposed solutions is larger than that from the standard formulae after vacuum preloading and is slightly samller after surcharge preloading. It is therefore recommended that the strength increase of soil mass acquired from standard formulae should be adequately readjusted. |
