摘　　要：本文根据基础梁的作用,分析了设计惯例的二种其对整体结构影响的计算方法,设置原则。提出基础梁设计标高及其构造要求。通过对基础梁设置的分析,认为其满足沿二个主轴双向拉结等条件时,底层结构计算高度应自梁顶面起算;当其仅外围及部分拉结等条件时,底层结构也可自梁顶面起算,但要求基础短柱加大截面做成柱墩,回填土应夯填,地面设计为刚性;当不符合以上要求,底层结构计算高度应自基础顶面起算。上述分析可供工程设计参考。This article according to the foundation beam the function, has analyzed design convention two kind of it to the overall construction influence computational method, the establishment principle. Proposes the foundation beam designed elevation and the structure request. Through to the foundation beam establishmenfs analysis, thought that it satisfies when bidirectional pulls along two main axles ties and so on conditions, the substructure tabulated altitude should from the Liang top begin reckoning; When it only periphery and the part pull ties and so on conditions, the substructure may also from the Liang top begin reckoning, but the request foundation short stump enlarge the section to make the stump, returns to the earth fill should hang to fill, the ground design is a rigidity; When does not meet the above requirement, the substructure tabulated altitude should begin reckoning from the foundation top. The above analysis may supply the engineering design reference.
