目前各规范中提出的地震荷载作用下边坡土压力的计算公式,虽然形式不同,但其实质上有许多相同之处,它们的主要区别是公式中所采用的系数不同。通过分析比较目前有关规范计算公式的工程适用性和各公式的差别,提出了拟入GB50330规范的地震土压力的计算公式。并通过试算的方法,对拟入GB50330规范计算公式和目前各规范计算公式进行了分析比较,从而论证了拟入GB50330规范计算公式的可信性和合理性。
At present, the formula for calculating earth pressure of slope under the seismic load proposed in various norms, though different in form, has many similarities in essence. The main difference between them is that the coefficients used in the formula are different. By analyzing and comparing the current engineering applicability of the standard calculation formula and the difference of the formulas, the formula of seismic earth pressure to be incorporated into the GB50330 standard is proposed. Through the method of trial calculation, the calculation formula of GB50330 code and the calculation formula of each standard are analyzed and compared, which proves the credibility and rationality of the calculation formula of GB50330.
