| 摘 要： | 通过在对8根预应力敞口管桩与闭口管桩的荷载-沉降试验,对比分析研究了敞口管桩与闭口管桩的沉降特性,并得出在桩顶荷载达到第3级荷载之前,两种桩的沉降几乎相同,随着继续加载,闭口管桩沉降与开口桩相比,沉降速度减缓,在达到管桩单桩极限承载力之前,闭口管桩沉降仅为敞口管桩的30%~50%左右.

| Abstract: | The settlement behavior in open-end and close-end piles was discussed in this paper based on the force-settle-ment test with eight specimens.It was concluded that the settlement speed of close-end piles was slower than the open-end piles and the settlement of close-end piles was only 30%~50% of settlement of open-end piles before the force arrived at the ultimate capacity. |
