天然气水合物分解对地层和管道稳定性影响的数值模拟

, 2008
利用ABAQUS有限元程序,对海底管道及其附近地层的应力和位移场随着水合物分解范围逐渐扩大的变化情况进行了数值模拟计算。结果表明,水合物分解对管道、地层的变形和应力分布的影响显著,随着水合物分解范围的扩大,管道和地层的变形显著扩大,管道由小变形逐渐变化为整体倾倒变形,即失稳。在工程设计中,为保证地层中管道的安全 ...

跨河跨堤建筑工程防洪影响分析

Renmin Zhujiang
为科学分析跨河跨堤建筑物与构筑物工程（如道路桥、铁路桥、输水/输油/输气管桥以及输电、通信线路等）对防洪的影响，以保障工程自身安全、维护防洪体系安全，并促进生态环境与人文景观的和谐共生。以梧桐山河碧道工程城韵梧桐段桥梁为例，通过水文分析计算、壅水和行洪能力分析计算、冲刷淤积计算、堤防及岸坡稳定分析计算等方法，评估桥梁对河道的综合影响。城韵梧桐段桥梁工程在满足防洪要求的前提下，能够实现生态保护与城市发展的协同目标。科学分析跨河跨堤建筑物与构筑物工程的防洪影响，对保障工程安全 ...
