采用打生石灰针加固路基土是一种较深层加固方法。曾经应用于局部或小面积的湿软路基土的处治,借以提高土基的承载能力。实践初步表明,改良效果好,但未推行。为了进一步研究“生石灰针方法”的可行性,现以学习日本国学者松尾新一郎提出的深层加固石灰桩方法的理论为依据,对“生石灰针方法”作了如下探讨。 1.设计原理松尾新一郎提出的石灰桩方法,它和砂井、挤压砂桩等方法的不同之处,是生石灰
The use of lime needles to reinforce subgrade soils is a deeper reinforcement method. Once used in local or small area of wet roadbed soil treatment, in order to improve the bearing capacity of the foundation. Preliminary practice shows that the improvement effect is good, but not implemented. In order to further study the feasibility of the “quick lime needle method”, the following discussion is made on the “quick lime needle method” on the basis of the theory of deep reinforcement lime pile method proposed by Japanese scholar Matsuo Shinichiro. 1. Design Principle Shinichiro Matsuo put forward the lime pile method, which and sand, squeezed sand pile and other methods of difference is the quicklime
