| 摘 要： | 对于地基主要受力层范围内局部存在软弱夹层的复杂地质条件，通常的处理方法或挖除换填或采用复合地基，针对具体工程探讨了的不同补强处理设计和施工方法的适用性，利用以往的研究成果，提出了按沉降控制进行补强设计的新思路，并针对处理后的深层复合土层不便直观和开挖检验的难题，结合多道瞬态面波法检验补强加固效果，实现了预期的目的，为类似工程实践提供了有益的借鉴。

| Abstract: | According to the complicated geology conditions of the foundation＇s main bearing stratum which partial contains weak intercalation, treatment methods are usually be used such as replacement method and composite foundation. Combined with practical work, some reinforcement designs are introduced and the applicability of the construction methods are discussed. In the base of the former research results, the new idea of reinforcement design through control settlement is been proposed. In view of the difficult problems that treated foundation is invisible and can not excavation to test directly, the multichannel transient surface wave method is be quoted firstly to test the reinforcement effects and the result is satisfied. It can be a useful reference for similar engineering practice. |
