Discussion on Bearing Capacity Difference of Natural Foundation and Pile Tip Resistence
-
摘要: 通过竖向荷载下土 (岩)体的破坏模式及其承载能力控制因素的比较,论述了物理力学性能相同的土层作为浅基础的天然地基与桩端持力层时,承载力值与桩端阻力值应存在一定的差异;而中 (微)风化程度的同一岩层作为天然地基与桩端持力层时,不具有这方面的差异性,承载力值与桩端阻力值应该相等。Abstract: Compared with soil destroyed pattern of vertical force and its controlled factor of bearing capacity,it is concluded that pile capacity and its tip resistence have some difference when soil with the same physical mecanic property is used as natural foundation and pile tip resistent layer.Whereas the middle weathering rod Stratum hasn't this property,that is to say it has the same bearing capacity and pile tip resistence.
