摘要
基于张季如提出的土工格室稳定分析模型,将其应用于京张高铁坡率为1∶0.3的高陡岩质边坡工程中,计算分析了不同坡率和固土深度工况下对土工格室材料强度的要求,并对边坡土工格室表面监测数据进行分析。结果表明:高强度的土工格室可在坡率小于1∶1.0的边坡上应用,而对于不同坡率的防护体系,土工格室强度要求尚需通过计算确定。
Based on Zhang Jiru's geocell stability model,geocell is applied to Beijing—Zhangjiakou high-speed railway high-steep rock slope protection project with the maximum slope ratio of 1∶0.3,which calculates and analyzes requirements of geocell material strength under different slope ratios and fixed soil depth,and through the analysis of the surface monitoring data of the slope geocell.The result shows that high strength geocell can be applied to slopes with slope ratio steeper than 1∶1.0.However,with respect to the protection systems for different slope rates,the strength requirements of the geocell need to be determined by calculation.
