文章通过倒虹吸工程管身地基处理实例,说明了水泥土搅拌法处理地基的设计关键,在于合理选择水泥土的无侧限抗压强度,进而确定搅拌桩的有效桩长,这两点关系到水泥土搅拌桩设计的安全性和经济合理性。对于小型建筑物的水泥土搅拌桩处理,可根据以往的类似地基土层性质的经验数据,比较合理地确定水泥土的抗压强度,而对于重要或者地基处理投资较大的建筑物,在设计前,应进行处理地基土的室内配比试验,以便更加合理地确定水泥土的强度参数,从而确保地基处理的安全和经济合理。
The article through the inverted siphon project pipe foundation treatment example shows that the cement soil mixing method to deal with the design of the key to the foundation, is to choose a reasonable cement soil unconfined compressive strength, and then to determine the effective length of mixing pile, these two points Safety and economic rationality of cement soil mixing pile design. For small-scale building cement mixing pile treatment, according to the previous experience of similar soil properties of the foundation, more reasonable to determine the compressive strength of cement-soil, but for important or foundation treatment of large investment in the design Before the test, it is necessary to carry out the indoor matching test of the foundation soil in order to determine the strength parameters of the cement soil more reasonably, so as to ensure the safety and economic rationality of the foundation treatment.
