灌溉诱发突发性黄土滑坡机理研究 总被引：1，自引：0，他引：1
系统揭示黑方台突发性黄土滑坡物理力学机理,对滑坡防治具有重要的作用。自上世纪六十年代年黑方台常年的农业灌溉诱发了大量20~40 m厚的饱和突发性黄土滑坡。本研究在野外调查的基础上,通过分析滑坡的变形破坏特征,针对分布范围广、危害性较大的突发性黄土滑坡,利用室内GDS三轴试验和模型试验,分析研究了饱和黄土的应力应变特性及突发性黄土滑坡的力学机制。三轴试验结果表明,当围压小于300 kPa时,饱和黄土可产生完全液化,并处于流塑状态;当围压大于300 kPa时,饱和黄土仅产生部分液化,仍具有一定的抗剪强度。饱和黄土的应力—应变模式均表现为强烈的应变软化—剪缩型,并具有一定的稳态特性。模型试验表明突发性黄土滑坡的变形破坏过程可大致分为底部浸水饱和—毛细水上升—持续蠕动变形—突发性破坏4个阶段。斜坡发生突发性破坏时,孔隙水压力激增,但总应力仍大于孔隙水压力,黄土滑坡发生部分液化,饱和黄土仍具有一定的强度,为突发性黄土滑坡发生提供了应力和能量积累的力学条件。研究从有效应力原理的角度阐述了突发性黄土滑坡的力学机理,可以为滑坡的防治治理提供一定的理论依据。 相似文献

黄土高原西部黄土工程物理性质及其成因 总被引：4，自引：1，他引：3
根据甘肃东部11个剖面黄土微结构、湿陷系数、凝聚力的测定和西安刘家坡剖面孔隙测定, 研究了黄土孔隙度、湿陷性、抗剪强度及颗粒成分在垂向上的变化规律和成因。结果表明, 孔隙度高、湿陷强和抗剪强度弱的层位是风化成壤弱的黄土层, 孔隙度低、湿陷弱和抗剪强度大的层位是红色古土壤或风化成壤强的黄土层。黄土地层工程物理性质在垂向上具有波动变化特征。第四纪冷干与温湿气候的交替和由此产生的成壤过程变化, 是造成黄土地层工程物理性质波动变化的根本原因。黄土湿陷性是在干旱与半干旱地区弱的成壤过程中产生的, 是草原地带灰黄色土壤具有的特征。在不同地区, 湿陷性黄土分布深度存在差别。干旱区分布深度比湿润区大。在干旱区, 强湿陷黄土分布深度可达12m, 中等湿陷黄土可达17m, 弱湿陷黄土可达20m以上。 相似文献

灌溉对甘肃中部黄土台塬区地面塌陷及生态环境影响研究 总被引：2，自引：2，他引：2
甘肃中部黄土台塬地面塌陷实质上是由水利灌溉引起的新的生态环境问题。文章在深入调查、勘测和试验研究的基础上，综合分析了地面塌陷变形的成因机制，认为黄土台塬地面塌陷变形除了黄土母质理化性质和人类活动等因素外，主要是不合理灌溉引起的。过量大水漫灌使大量渗入的水体将土壤中起固结作用的盐分和粘粒矿物淋溶殆尽，使原始结构破坏，进而崩解、湿陷。随下渗水量的增加，犁底层及以下隔水层孔洞进一步发展为洞穴和陷缝，大面积塌陷变形随之出现，同时也成为台塬滑坡的诱导因素。研究为黄土台塬灌区突出的水利环境问题治理和生态重建方案提供了基础依据。 相似文献

分析了伊犁谷地28个黄土样品的粒径、密度、含水量和孔隙比,测试了震陷、湿陷、动弹模量和塑性指数,探讨了伊犁谷地黄土的物性、动力学特征,讨论了它们与滑坡之间的关系。伊犁谷地的原生黄土主要以粉粒为主,含量为74%,大于75μm的颗粒含量为10%,小于5μm的颗粒含量为15%;黄土天然含水量为4%~16.1%,谷地东部的黄土明显地比谷地西部的更细,伊犁黄土的孔隙比在0.832~0.907之间,有相当的湿陷性。在含水量低于20%时,还会有湿陷。黄土的塑性指数为9左右,比较小,粘粒含量低,易损性大,抗震性能差,具有较强的震陷性。在同样的动应变下,伊犁黄土的动模量较小,随着动应变的增大,其动模量衰减较快。冻融季节是伊犁地区滑坡的多发季节,构造活动强烈的地段也是地质灾害的多发地段。 相似文献

针对当前黄土地区公路自然区划宏观程度高、实际难应用等问题,研究新的区划方案、寻找理想的区划指标意义重大。以分形理论为基础,分析了甘肃黄土粒度分布的分形结构特征。结果显示,黄土具有良好的统计自相似性,其分维值介于2.15~2.705之间;黄土的粒度分维值可定量表征黄土的物理、力学和水理性质及差异,即黄土的粒度分维值越大,其干密度、比表面积、粘聚力、内摩擦角越大,微、小孔隙含量越高,但其平均孔径、孔隙比、湿陷系数和渗透系数越小,其工程地质性质愈稳定;在空间上,黄土粒度分维值存在显著的区域性变化规律,反映了甘肃黄土地区二级公路自然区划的5个二级区的差异。认为黄土粒度分维值可作为公路自然区划的主要指标之一,参与三级区的划分,为公路工程的设计、施工提供科学依据。 相似文献
