摘要:
通过应力控制式循环三轴试验, 探讨了地铁行车荷载作用下饱和黄土的累积塑性应变.试验表明:饱
和黄土累积塑形应变存在三个典型的发展阶段, 即:衰减阶段、稳定阶段和破坏阶段.固结围压、循环试验中的
排水条件、动应力及其循环次数、以及动应力比是影响饱和黄土累积塑性应变的重要因素.在排水循环三轴试
验中, 饱和黄土的累积塑性应变随初始固结围压的增大而减小, 随循环次数、动应力和动应力比的增大而增
大.基于试验数据, 建立了预测饱和黄土累积塑性应变的反正切函数模型.该模型与试验数据符合良好, 且仅
需三个土体参数, 应用比较方便.
Abstract:
Ba sed on the st ress contr ol cyclic triax ial te sts , the cumulative plastic str ain o f saturated loess due to metr o traffic
lo ading ha s been investig ated under different co nsolidatio ns .The develpoment o f cumulative plastic strain can be divided
into three stag es, i.e .attenua tion , stabiliza tion and damag e .The primitiv e co nso lidatio n pressure , drainag e co ndition
in cy clic triax ial tests, dy namic stress and its vibra tion times , and dy namic stress ratio a re pr edomina nt facto rs in the dev
elo pment of cumulative plastic strain of sa turated loe ss .In drained cyclic triaxial tests, the cumulativ e plastic strain o f
sa tur ated loess w ill inc rease w ith the dy namic stress, vibratio n times, and dy namic stress ratio , but it will decrea se with
primitive co nsolidatio n pressure .Finally a ca lculatio n model wa s established to predict the cumulative plastic str ain o f satura
ted loess.This model require s o nly three parame te rs and matches the test da ta w ell .
