摘要
在常州地区土钉墙破坏模式及坡比变化影响分析的基础上,以该地区常见地质条件为例,对土钉墙坡比与基坑整体稳定性、工况稳定性及支护费用的关系进行研究,结果表明,土钉墙坡比为0.4~0.6时,基坑整体稳定性和支护费用达到最优,该结论对常州地区土钉墙的设计有一定的技术及经济参考意义。
The impact of the slope ratio on the failure modes of the soil nail wall in Changzhou soils is carefully analyzed based on the typical subsurface conditions.The influence of the slope ratio of the soil nail wall on the global stability of the deep excavation as well as the construction cost are investigated.The results indicate that the global stability and the cost effectiveness can be achieved when the slope ratios are in the range from 0.4to 0.6.
