【摘要】 为节约资源,关于湿陷性黄土层桩基负摩阻力的取值问题有必要作进一步探讨,本文基于规范及地勘报告中对湿陷性黄土层中桩基摩阻力取值问题,分析了国内工程界所做的多次湿陷性黄土层负摩阻试验结果,并结合西安市十里铺及东北二环立交湿陷性黄土层摩阻试验情况及设计时的取值探讨,指出了目前设计中湿陷性黄土层负摩阻取值存在的不合理因素。更多还原

【Abstract】 In order to conserve resources,the question on collapsible loess negative friction value should be further discussed.On the question of side friction value around the pile in collapsible loess about specification and geological prospecting report,the result of several tests about collapsible loess negative friction in domestic engineering was analyzed in this paper.Consulting actual projects side friction around the pile tests on collapse loess layer of shi li-pu and northeast second ring interchange of xi’an and final designing value,unreasonable factors of collapsible loess negative friction value in designing now were put forward.更多还原
