摘要:
为探究高聚物密度对高聚物-粉土界面接触形态及界面剪切特性的影响机制，采用界面无损分离与三维激光扫描相结合的方法，开展了高聚物-粉土三维界面形貌特征扫描试验，得到了不同密度下的界面粗糙度参数。结合界面直剪试验，研究了不同高聚物密度影响下高聚物-粉土界面粗糙度参数、界面剪切应力-位移关系、界面剪切力学强度参数及界面粗糙度参数与界面剪切强度的变化规律。在此基础上，利用COMSOL软件建立了一种随机三维粗糙界面有限元模型，进一步探讨了不同界面粗糙度下高聚物-粉土界面剪切损伤机制。结果表明：基于三维界面重构的有限元数值模型可准确地预测不同密度下高聚物-粉土界面剪切应力-位移关系，且高聚物-粉土界面在直剪荷载下的主要损伤特征表现为界面凸起处形成的应力集中，密度越大凸起点越多，应力集中越明显。高聚物-粉土界面粗糙度和剪切强度均随高聚物密度的增大而增大，且高聚物-粉土界面粗糙度和剪切强度满足线性关系。
Abstract:
To investigate the influence mechanism of polymer density on the contact morphology and interfacial shear properties of polymer–silt soil interface, using a non-destructive method for separating interfaces, combined with three-dimensional laser scanning, the scanning test of three-dimensional interfacial topographic features of polymer-silt was carried out, and the interfacial roughness parameters were obtained under different densities. Combined with the interfacial direct shear test, investigated under the influence of different polymer density, polymer-silt interface roughness parameters, interfacial shear stress-displacement relationship, interfacial shear mechanical strength parameters, and the change laws of interfacial roughness parameters and interfacial shear strength. Based on this, a finite element model of a random three-dimensional rough interfacial was established by using COMSOL software to further explore the shear damage mechanism of polymer-silt soil interface under different interfacial roughness. The results show that the finite element numerical model based on three-dimensional interface reconstruction can accurately predict the shear stress-displacement relationship of polymer–silt soil interface under different densities, and the main damage feature of polymer–silt soil interface under direct shear load is the stress concentration formed at the interface bumps, and the greater the density, the more the bumps, and the more obvious the stress concentration. The roughness and shear strength of the polymer-silt soil interface increase with the increase of polymer density, and the roughness and shear strength of the polymer-silt soil interface satisfy the linear relationship.
