复杂地质条件下岩石地基承载力预测

Prediction of bearing capacity of rock foundation under complex geological conditions

为了提升复杂地质条件下地层岩石地基承载力的预测精度,提出一种新的岩石地基承载力预测方法。组建地层岩石地基复杂地质条件预测模型,设计不同地质条件下岩石地基压力强度分析指标,综合分析复杂地质条件,结合高斯随机过程与贝叶斯学习理论,实现岩石地基承载力的预测。实验数据分析表明,应用设计方法预测的岩石地基承载力可以最大限度地趋近实际承载力数值,且误差控制效果与预测误差的收敛性、稳定性均能够满足相关强度准则的指标要求,具有较好的应用性能。

In order to improve the prediction accuracy of stratum rock foundation bearing capacity under complex geological conditions,a new prediction method of rock foundation bearing capacity is proposed in this paper.Establish the prediction model of complex geological conditions of stratum rock foundation,design the analysis index of pressure strength of rock foundation under different geological conditions,comprehensively analyze the complex geological conditions,and realize the prediction of bearing capacity of rock foundation by combining Gaussian random process and Bayesian learning theory.The analysis of experimental data shows that the prediction result of rock foundation bearing capacity by using the design method can approach the actual bearing capacity value to the greatest extent,and the error control effect and the convergence and stability of prediction error can meet the index requirements of relevant strength criteria,which has good application performance.
