| 摘 要： | 土工格室被应用于道路、地基、边坡与渠道的保护以及重力式支挡结构，其中，加筋地基可以通过格室侧壁的限制和摩擦力改善砂、石等填料的工程性质，将土工格室层视为基础的旁侧荷载可提高地基承载力。根据土工格室加筋土体的力学机理，采用极限平衡分析法，利用三角形条块法求作用在三角形刚性楔形体两滑动剪切面上的被动土压力，并考虑了土体与土工格室侧壁相互作用对地基承载力的贡献，提出土工格室加筋软基承载力公式，并采用已有模型试验结果，验证了公式的合理性和正确性。

| Abstract: | Geocell has been widely used in civil engineering in recent years.The mechanism of geocell reinforcement system mainly includes that geocell confining system makes the reinforced soil shows an apparent cohesion due to its membranes effect and hoop stress,and stress diffusion of geocell reinforcement system which make the bearing capacity of reinforced soil improve considerably.Considering the mechanism of geocell reinforcing soil,using limit equilibrium analysis method,the formula of bearing capacity of geo... |
