建设部通知试行的《饱和轻亚粘土液化判别暂行规定》(以下称“规定”),我们经过几年的试用,效果良好,实用。它的判别式用于砂土和轻亚粘土,可通过计算液化指数评价液化等级,明确表示液化程度。但是,“规定”也有不足之处:如液化指数P_L的计算仅为单孔的方法和示例,未能规定多孔(剖面上、平面上)的计算原则。此外编制说明表(2)的计算结果有误。
The Provisional Regulations on Liquefaction of Saturated Light Sub-clay (hereinafter referred to as “provisions”) notified by the Ministry of Construction will be tried. After several years of trials, the results are good and practical. Its discriminant formula is used for sand and light sub-clay. Liquefaction grade can be evaluated by calculating liquefaction index, and liquefaction degree can be clearly expressed. However, the “regulations” also have shortcomings: for example, the calculation of the liquefaction index P_L is only a single-hole method and an example, and the calculation principle of the porous (in-plane and in-plane) cannot be specified. In addition, the calculation result of the preparation statement (2) is incorrect.
