桩是一项传统技术,桩基仍在不断发展创新。我省水利工程使用桩基的为数不少,但对一些问题的认识并不一致,现就接触到的情况,发表一点意见,以引起讨论。一、桩侧摩阻力的基本概念桩侧摩阻力似乎是桩壁与土之间的摩阻力,其实并不完全如此。钻孔灌注桩的桩侧摩阻力一般为桩侧土的抗剪强度。这是因为混凝土向钻孔中灌注 Piles are a traditional technology, and pile foundations are constantly developing and innovating. There are a large number of pile foundations in our province’s water conservancy projects, but the understanding of some issues is inconsistent. We are now talking about the situation and we have made some comments to discuss. First, the basic concept of side friction resistance Pile side friction seems to be the friction between the pile wall and soil, in fact, is not exactly the case. The pile-side friction resistance of bored piles is generally the shear strength of pile-side soil. This is because the concrete is poured into the borehole
