石灰桩是一种加固松软地基的方法,属于挤密法。我国在五十年代就开展了这种方法,由于施工工艺未能很好解决,因此停滞了一段时间。近年来在杭州、南京、天津、西安等地,改进了施工工艺,并应用于施工实践中,集累了经验,取得了较好的经济效益,是值得推广的加固方法。为了使现场施工人员了解此法的加固机理、设计计算、施工工艺,本刊组织了这次讲座,供施工、设计时参考。
Lime pile is a method of strengthening soft ground, belonging to the squeeze method. This method was carried out in the 1950s in our country. Due to the construction process was not well solved, it stagnated for some time. In recent years, Hangzhou, Nanjing, Tianjin, Xi’an and other places to improve the construction technology, and applied to the construction practice, accumulated experience, and achieved good economic returns, is worth promoting the reinforcement method. In order to enable on-site construction workers to understand the law of reinforcement mechanism, design and calculation, construction technology, the magazine organized the lecture for construction, design reference.
