本文针对土工格室结构层剪切性状研究成果有限的现状,通过大比尺模型试验方法,研究了不同填料、不同剪切面、不同焊距的土工格室加筋层和未加筋填料的似粘聚力和摩擦角特征。结果表明:土工格室结构层的平面剪切试验与斜面剪切试验相比,由于加筋体的直接参与,斜面剪切强度比平面剪切强度高的多;从提高的强度来说,主要体现在似粘聚力得到提高,内摩擦角提高不大;不同型号的土工格室加筋以后,格室结构层之间的抗剪强度提高幅度无明显区别。
In this paper, according to the limited research status of the shear properties of the geocell structural layer, the geostrophic reinforced layer with different fillers, different shear planes and different welding distances and the non-reinforced filler Like cohesion and friction angle features. The results show that the shear strength of the geocell structural plane is much higher than that of the plane shear strength compared with the slope shear test because of the direct participation of the stiffened body. From the perspective of increased strength, Reflected in the cohesion is improved, the internal friction angle increase is not big; different types of geocell reinforced, lattice structure layer between the shear strength of the increase was no significant difference.
