摘要
对断层在土体中的传播模式及其对地下管线的影响研究进行了综合评述,国内外很多学者通过现场调查、室内模型试验、离心试验以及数值计算对断层在土体中的传播模式和对地下管线的影响进行了深入的研究,由于试验手段和数值计算手段的局限性,对断层在土体中的传播模式和对地下管线的影响还不能进行定量化分析.为了研究活断层引起地震对环境的影响,指出了目前存在的问题以及需要进一步开展的研究,对深入研究断层在土体中的传播及其对地下结构物和地表结构物的影响,以及结构物的抗震设计及其危险性评价具有重要意义.
The propagation of patterns of fault in soil and its influence of fault movement on buried pipelines are reviewed. Model experiment and numerical simulation have been used to study patterns of rupture qualitatively due to their limitations. The issues for further studies on this subject are indicated.
