| 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.在A. S. Vesi'c极限承载力公式和R. M. Koerner公式的基础上,提出了土工格室加筋地基承载力的改进公式,并用算例分析了其加筋效果.

| Abstract: | Geocell mattresses have been successfully used in stabilizing foundations, embankments, retaining walls and slopes. Among them, in reinforced foundation the performance of sand or stone filled in geocell is improved by confinement and friction of lateral cell walls, the layer of geocell can be taken as the surcharge on the base of footing which will improve the bearing capacity. Based on Vesi'c's ultimate bearing capacity equation and Koerner's ultimate bearing capacity formula for foundation reinforced with geocell, a modified formula is put forward. The effect of foundation reinforced with geocell and without it is illustrated by examples. |
