前言对地震反应的研究日益广泛,促使了发展一种可靠的、能原位测定剪切模量的技术。本文叙述了两种剪切波测定技术,能原位测定供地震分析用的剪切模量,公式为:G=ρV_s~2 (1)如已知剪切波速 V_s 和密度ρ就可计算得剪切模量 G。Mooney 总结了这一理论,并提出在工程中如何应用地震剪切波的问题。Stokoe 和 woods 编录了有关跨孔法、孔内激振法和孔口激振法的参考文献。Hardin Introduction Research on seismic responses has become increasingly widespread, prompting the development of a reliable, in-situ measurement technique for shear modulus. This paper describes two kinds of shear wave measurement techniques and can measure the shear modulus for seismic analysis in situ. The formula is: G=ρV_s~2 (1) If the known shear wave velocity V_s and density ρ can be calculated Shear modulus G. Mooney summarized this theory and proposed how to apply seismic shear waves in engineering. Stokoe and Woods have cataloged references for cross-hole, in-hole excitation, and orifice excitation methods. Hardin
