【摘要】 当天然地基不能满足建(构)筑物设计要求时,需要对其进行地基处理,形成人工地基,以满足建(构)筑物的安全与正常使用。人工地基包括复合地基和桩基础。在地震设防区建造高层建筑时,对承载力低、压缩性高及存在有液化土层的地基,研究探讨人工地基设计,是一件很有实际意义的工作。对现有规程规范进行了全面深入研讨和分析,并通过一工程实例在现有规程规范的基础上进行优化设计,做到设计方案技术先进可行、经济合理,为以后类似工程设计提供参考。更多还原

【Abstract】 When natural subgrade can not be satisfied the requirements of building design,We need to take ground treatment for its safe and normal use, Artificial subgrade include composite subgrade and pile foundation. when high-rise building locate at earthquake fortification area,for low supporting capacity,high compression or liquefied soil subsoil, Artificial subgrade design research become a engineering significance valuable work . This paper has inspected and analyzed the existing codes and standards, based on comprehensive and correct understand to the codes and standards. Has given a project example optimization design,the design plan is advance in technology,economy is reasonable, provides a reference for the later similar engineering design.更多还原
