变径基础桩的初探研究

Original Study on changing diameter of fundamental piles

结合工程实际,提出采用变径基础桩,并通过计算变径基础桩的强度(承载力)和变形(沉降),与非变径基础桩比较,然后对变径基础桩的优缺点进行探讨研究,论证了变径基础桩的可行性。

In the light of project＇s fact, the paper puts forword to adopt changing diameter of fundamental piles when they are fundamental piles of tall buildings, and calculates defomnation（settlement） and strength（bearing capasity） of changing diameter of fundamental piles, and compares with calculating outcomes of unchanging diameter of fundamental piles. Then inquires into defects and merits, and proves feasiblility of changing diameter of fundamental piles.
