摘要
通过对几根试桩的孔径曲线和极限承载力进行比较，从中发现，孔壁形状凹凸不平的桩比孔壁形状平直、光滑的桩具有更高的承载力。孔壁形状因施工工艺不同而不同，通过孔径测试，可以及时发现施工工艺中的问题。
Through compariosons among curves of radii of holes and bearing capacity of several piles it is found that the bearing capacity of pile with uneven hole wall is higher than that of pile with smooth hole wall.The shape of hole wall is varied accoirding to construction process.
