现行的地基处理方法可以分为浅层处理法和深层处理法,此两种方法处理完成后均要求地基承载力达到一定设计值,即一步到位的处理方法。一步到位的地基土处理方式,完全忽略了地基土在使用过程中的固结,没有充分发挥地基土在固结后的承载力。根据上海港罗泾矿石码头堆场地基土使用前和使用几年后的对比,浅层地基土固结后承载力可提高20%左右。
The existing foundation treatment methods can be divided into shallow treatment method and deep treatment method. Both of these methods require the bearing capacity of foundation to reach a certain designed value after the two methods are completed, that is, the one-step treatment method is adopted. One-step treatment of foundation soil completely neglects the consolidation of foundation soil during its use, and does not give full play to the bearing capacity of foundation soil after consolidation. According to the comparisons of the foundation soil of Luojing ore terminal yard in Shanghai before and after several years of use, the bearing capacity of shallow foundation soil after consolidation can be increased by about 20%.
