笔者在工程设计的实践中,曾遇到几例在软弱地基条件下的工程,因在基坑开挖过程中,发现地下暗沟、暗管(地质未探明)等难以处理,并影响周围建(构)筑物安全的地基,、采用常规地基加固方法进行补救,动用机械,不仅施工难度大,投入时间长,投资也比较大。故笔者结合当地松木资源较多的实际情况,经计算比较,采用人工打入2.5～3m木桩 In the practice of engineering design, the author encountered several projects under the conditions of soft foundation. During excavation of the foundation pit, it was found that it was difficult to deal with the underground ditches and concealed pipes (Structure) building safety foundation, the use of conventional foundation reinforcement methods to remedy the use of machinery, construction is not only difficult, long time, investment is relatively large. Therefore, the author combined with the actual situation of the local pine resources more, by comparison, the use of artificial into 2.5 ~ 3m stake
