本文利用实测的标准贯入阻值经过修正,取得有效压力σ_0′为1公斤/厘米~2情况下的标准阻抗击数N_1作为砂土原位抗液化参数。再根据地震实际资料,从工程地质角度对饱和砂土的液化土型进行分类,对其中可能液化土型的砂找出在不同地震剪应力作用下的液化临界标准阻抗击数[N_1]。 This article uses the measured standard penetration resistance to be modified to obtain the standard resistance number N_1 in the case of an effective pressure σ_0′ of 1 kg/cm 2 as the in-situ anti-liquefaction parameter of the sand. According to the actual seismic data, the liquefied soil types of saturated sand are classified from the perspective of engineering geology, and the critical liquefied standard impedance number [N_1] under different seismic shear stress is found for the possible liquefied soil type sand.
