【摘要】 地震时砂土地基的液化对地下管道构成威胁,土壤液化有各种不同的因素,这些因素间相互关系较为复杂,很难精确评估或预测土壤液化对地下管道产生的影响。通过对埋地管道抗液化措施模型试验,观察和测量模型管及地基的变化情况,验证了几种有效的抗液化措施,找出了液化状态时饱和砂的密度,为抗液化计算提供参考。更多还原

【Abstract】 The liquification of soil foundation from earthquake impacts significantly the buried pipeline. The different factors result in soil liquification, and the relationship between the factors is very complicated, which is hard to evaluate and predict the impact of soil liquification on buried pipeline. The model test of anti-liquification of soil for buried pipeline is made. On the basis of observation and measurement on the variation of model pipe and foundation,the density of saturated soil in liquification state is found,which can provide useful data to anti-liquification of soil calculation. Some effective measures on anti-liquification of soil are summarized.更多还原
