| 摘 要： | 本文对唐山市信息港工程进行沉降观测试验研究。沉降观测布设高程控制网点共5个,共观测6次,另外监测7次,实际观测13次。通过对沉降观测进行分析,从群桩沉降时间关系曲线可以看出,沉降的总趋势是沉降速率随时间的增长而衰减,最后趋于基本稳定,图中出现的沉降曲线上下波动,作者认为是由于群桩中各部分荷载的重新分配造成的。

| Abstract: | This paper introduces experimental investigations of settlement observation to the project of information harbor in Tangshan City.The settlement observation needs to arrange five height control stipples,totally observes 6 times,moreover monitors 7 times,and actually observes 13 times.After analysising towards settlement observation,the total settlement trend is that rate of settling is decaying along with the growing time from the curve of the relationship of settle-time,and finally intends to stability,and the settlment curve is top and bottom wave motion.The author thinks it is because of the reallocation each parts of loads of the pile cluster. |
