衡枣高速公路盘古祠边坡稳定性分析

盘古祠边坡由于边坡初步设计不合理，2002年4月出现了滑坡，体积达万余m^3，滑坡治理费达40万元．为了对设计和施工起到超前预报与辅助决策的作用，本文对大量边坡工程实例进行了集成，建立了预测安全系数的ANN模型，并应用ANN技术对盘古祠边坡设计方案的Fs进行了计算，结果表明，初步设计方案导致滑坡是必然的．同时又进一步对治理后的边坡进行了Fs预测，治理方案由于Fs值较高，则是可行的，能保证更改设计后的边坡稳定。

Stability Analysis of Pan-Gu Temple Slope Beside Henyang-Zaomupu Highway

Pan-Gu Temple slope became failure in April,2002 with the volume of more than 10,000 m~3 because of the unreasonable original design.The father charge had come to (40,000)yuan(RMB).In order to enhance forecast and assistant decision-making,we integrated a lot of slope engineering examples,built a ANN model to forecast the safety factor and calculate Fs of Pan-Gu slope design scheme with ANN technology.The results show that the original design surely leads to coast and that the father design can keep the changed slope stable with the higherd Fs value.
