Efficient Meshfree Simulation of Large Deformation Rainfall-Induced Soil Slope Failure [PDF]

open access: yes, 2009
本文深入研究了稳定节点积分伽辽金无网格法的变分构造,在假定应变理论的架构下,提出并比较分析了三种应力计算方法:(1)基于位移梯度的节点应力计算方法;(2)基于光滑应变的节点应力计算方法;(3)基于光滑应变的一致形心应力计算方法。典型数值算例表明,满足变分一致条件与否和精度高低没有必然联系,三种应力计算方法中基于光滑应变的一致形心应力计算方法的精度最高。另外,在稳定节点积分基础上建立了用于饱和土体中稳态渗流分析的伽辽金高效无网格方法,所构造的节点非局部光滑水力梯度不仅具有节点积分效率高的优点 ...

Preliminary analysis on characteristics of water and sediment movement and environmental disasters changes in the Three Gorges reservoir area [PDF]

open access: yes, 2009
三峡水库自2003年蓄水以来,积累了大量实际观测资料,为研究库区水沙运动特性及环境问题提供了有利条件.本文基于水库实际运用情况,对水库蓄水后的洪水波传播、悬移质泥沙运动、库区富营养化以及库岸滑坡灾害等的主要变化进行了初步分析,表明三峡水库蓄水运用后,这些方面发生了较大的改变,并呈现出新的特点,对三峡工程的长期运行有一定影响,其中反映的重要问题值得深入研究,并在今后的工程运用中应给予足够的重视 ...
