天然地基抗压刚度系数C,在机器基础的动力计算中占有十分重要的地位,其取值是否准确,直接影响到动力基础计算振幅值的准确性,因此也是关系到基础设计的合理性和可靠性问题,对设计者来说必须予以重视。苏联在1970年《动力机器基础设计规范》(以下简称《动规》)中规定:“天然地基的弹性均匀压缩系数C_Z由土壤试验结果确定。如无试验资料,为了预先计算,C_Z值可根据地基的标准强度R~H按表1采用。”
The natural foundation compressive rigidity coefficient C occupies a very important position in the dynamic calculation of the machine foundation. The accuracy of its value directly affects the accuracy of the amplitude calculation of the dynamic foundation, so it is also related to the rationality and reliability of the basic design. Sexual issues must be valued by designers. In 1970, the Soviet Union stipulated in the “Code for the Design of Power Machine Basics” (hereinafter referred to as “the motion regulation”): “The elasticity uniform compressibility coefficient C_Z of the natural foundation is determined by soil test results. If there is no test data, the C_Z value can be based on The standard strength R~H of the base is used according to Table 1."
