摘要

围岩类别超前分类是隧道施工过程中必须开展的一项工作，其直接关系到后续的开挖及施工支护方案。为有效地进行隧道围岩类别超前分类，提出了基于数字钻进技术和量子遗传（QGA）-径向基函数（RBF）神经网络的围岩类别超前分类方法。以数字钻进技术为基础，从钻进参数中提取有用信息，构建围岩类别超前分类指标体系。采用量子计算原理对遗传算法进行改进，通过量子位编码和量子旋转门更新种群，以此来确定RBF神经网络的参数，建立了基于QGA-RBF神经网络的围岩类别超前识别系统。最后将该方法应用于青岛胶州湾海底隧道的围岩类别超前识别中，结果表明，该方法具有较高的准确性，其结果为围岩类别超前分类提供了一种新思路。

Abstract

Conducting the advanced surrounding rock classification is a necessary working in the process of tunnel construction

which is directly related to subsequent excavation and supporting construction scheme. In order to conduct surrounding rock classification ahead tunnel advancing effectively

the advanced surrounding rock classification method based on digital drilling technology and quantum genetic algorithm (QGA)-radical basis function (RBF) neural network is put forward. The method extracts useful information from the drilling parameters; and it establishes the indicators system of advanced surrounding rock classification. In the progress of establishing advanced surrounding rock classification index system based on QGA-RBF neural network

the genetic algorithm are improved by quantum calculation principle; and the parameters of RBF neural network could be determined by quantum bit and rotation gate renew population. Finally

the method is applied to the subsea tunnel across Qingdao Jiaozhou bay engineering. The results show that the method has higher prediction accuracy and provides a new idea in advanced prediction of surrounding rock classification.
