新型固化剂ESC在搅拌桩中的应用研究

通过新型岩土固化剂（ESC）搅拌桩体与水泥土搅拌桩体的对比试验以及ESC固化土作用机理的论述，说明了搅拌桩具有较高的侧摩阻力，同时证明了用ESC固化剂替代水泥能使搅拌桩固结土的强度大幅度得到提高，从而解决了搅拌桩因桩体强度低而存在的侧摩阻力难以发挥、单桩承载力低的问题。

On application of new ESC solidifying agent to mixing piles

By way of contrast tests for on the new type of ESC mixing piles body with the soil-cement mixing piles body, the mechanism of ESC solidified soil is expounded; and that these mixing piles have higher side friction is proved. Meanwhile, that substituting the ESC solidifying agent for cement can obviously increase the strength of solidified soil in the mixing piles is proved. Therefore this method has naturally solved the following problem, that is, the single use of cement can’t allow full play to the side friction because of low strength of the bodies of mixing pile and low bearing capacity of the single pile.
