摘要

本文介绍了土的饱和度对土工格栅拉拔性能影响的试验研究结果。在进行试验时,考虑了不同的试验变量,包括基于含水量的土壤物理条件和施加的外部载荷。使用的土壤是当地可用的风化花岗岩土。试验包括90%、80%、70%和45%(最佳含水量)的饱和度变化。拔出试验按照ASTM标准D 6706-01进行。结果表明:土体饱和程度的增加会降低拉拔能力,从而降低界面摩擦角和相互作用系数;根据土的正常载荷和饱和程度的不同,拉拔界面系数的减小幅度在12.50% ~ 33.33%之间。试验结果表明,增加加筋土内部的饱和程度会对加筋的拉拔行为产生不利影响,从而影响其内部稳定性。并详细分析了所得结果的实际推论。

Variation of Pull-out Resistance of Geogrid with Degree of Saturation of Soil
This paper presents the results of experimental investigation on the effect of degree of saturation of soil on the pullout behavior of a geogrid. Different test variables were taken into account while performing the experiment including the soil physical conditions based on water content and external loading applied. The soil used was locally available weathered granite soil. The tests included variations in saturation of about 90%, 80%, 70% and 45% (optimum moisture content). The pullout tests were performed according to ASTM standard D 6706-01. The results indicate that increasing the degree of saturation in the soil decreases the pull-out capacity, which in turn decreases the interface friction angle and interaction coefficient. The decrease in the pullout interface coefficient was observed to be around 12.50% to 33.33% depending on the normal load and degree of saturation of the soil. The test results demonstrated the detrimental effect of increasing the degree of saturation within the reinforce soil on the pullout behavior of reinforcement, thus on the internal stability. The practical inferences of the outcomes are analyzed in detail.
