该文根据《建筑抗震设计规范》等国家技术标准的规定,结合江苏地区电力工程的勘察经验以及国内外最新的理论研究成果,对饱和砂性土液化判别与计算中存在的几个问题进行分析,针对上覆非液化土层厚度的确定、粘性土互层与夹层的考虑、以及6度区对沉陷敏感的乙类建筑的规定等问题作了一些探讨,旨在为砂性土的液化计算积累一些有益的经验。
According to the requirements of national technical standards such as Code for Design of Seismic Design of Buildings, combined with the survey experience of power engineering in Jiangsu Province and the latest theoretical research at home and abroad, several problems in the identification and calculation of liquefaction of saturated sandy soil are analyzed , Some problems such as the determination of the thickness of overlying non-liquefiable soil layer, the consideration of cohesion and interlayer of cohesive soil, and the regulation of subgrade B sensitive to subsidence in 6 degree area are discussed in this paper. The purpose is to calculate the liquefaction of sandy soil Accumulate some useful experience.
