对湿陷性黄土场地地震作用工程影响的几点看法

Some Opinions on Effect of Engineering under Earthquake Action in Site of Collapsible Loess

摘要:

针对《建筑抗震设计规范》(GB50011-2001)中涉及黄土的规定,提出了看法和改进意见,就地震作用对工程的不利影响(如震陷、液化、基桩负摩擦力等),进行了分析并提出相应的工程建议;特别强调地震作用对工程影响必须考虑湿陷性黄土的含水状态。

Abstract:

Some views and improvement opinions for stipulations ralate to loess in ＂Code for seismic design of buildings＂（ GB50011-2001） are put forward. The unfavorable effects of earthquake action to engineering （such as seismic subsidence of loess, liquefaction, negation friction of pile, and so on） are analyzed, and some relative engineering suggestions are given. For special emphasis, the water-bearing state of collapsible loess must be considered when dealing with the effects of earthquake action to engineering.
