Description

基于长石特征的隧洞内碎屑岩抗风化能力判别***与方法 技术领域
本公开属于岩土抗风化测试领域，涉及一种基于长石特征的隧洞内碎屑岩抗风化能力判别***与方法。
背景技术
本部分的陈述仅仅是提供了与本公开相关的背景技术信息，不必然构成在先技术。
长石类矿物是地壳中最为常见的硅酸盐矿物，作为岩石圈最为重要的造岩矿物，其特征与岩石的结构构造、硬度、抗压程度以及其抗风化能力有着非常紧密的联系，由于长石的结晶温度较低，仅次于石英和白云母，因此在自然界中属于抗风化能力较强的一类矿物。但传统方法对岩石硬度或其抗风化能力的研究多集中于对石英的考量，对长石与岩石抗风化能力的相对关系考虑很少，但是长石在岩石圈中的分布更为广泛，如果需要考虑尽可能找到一个可以适应于多种岩石的矿物因素，长石不失为一个很好的选择。
碎屑岩中的矿物多数是由岩浆岩风化后经过搬运而沉积的，长石作为已经风化后的产物而继续保存下来，说明其有很强的抗风化能力，尽管碎屑岩中同样也存在大量的石英，但长石对碎屑岩抗风化能力也同样有非常重要的影响。但据发明人了解,目前对于碎屑岩抗风化能力的评价中,缺少长石特征的考虑,而缺少对长石特征的考虑，致使所能研究的岩石类别较少，同时会出现利用少量的石英含量来推测岩石的抗风化程度等现象，导致观测的误差范围较大。
发明内容
本公开为了解决上述问题，提出了基于长石特征分析的隧洞内碎屑岩抗风化能力判别***与方法，本公开通过研究隧道碎屑岩中长石的特征来判断其抗风化的能力，填补了研究隧道围岩在抗风化能力方面预测研究的空白。

如图1所示，基于长石特征分析的隧洞内碎屑岩抗风化能力判别***与方法，其包括数据采集***、无线传输***、数据分析***、数据输出与存储中心，各个***中又包含有不同模块。
如图2、图3和图4所示，数据采集***中的取样机构、自动扫描模块和元素分析模块通过机械臂安装于TBM前端，其中取样机构和自动扫描模块可在TBM停机时对掌子面进多方位随机取样以及全方位图像采集；
元素分析模块搭载有X射线分析仪，对岩石中所含基本化学元素信息进行采集；
此外，显微图像模块和矿物定量模块置于远程控制实验室，其所获得的数据传送至深度学习模块；
其中显微图像模块搭载有高分辨率的偏关显微镜主要用以提取长石的解理特征、干涉色特征、突起特征以及晶体结构特征以传输给学习模块进行分级；
矿物定量模块搭载电子探针***，由于X射线***只能半定量的测量元素类别，无法定量研究，因此探针***可进一步定量分析各类长石的含量以供学习***开展分析并定级；
无线传输***搭载于信息采集***末端，用以将采集***中自动扫描模块和元素分析模块获得的数据传输至数据分析***；
数据分析***至于远程控制室，包括岩性对比模块与深度学习模块；
其中岩性对比模块接收来自数据采集***的信息，通过与深度学习模块协同工作；
岩性识别***嵌入了岩性库，学习模块通过提取图像特征以及元素特征后可以反馈出基本的岩性信息；
深度学习模块包括人工辅助神经网络训练器以及自动模型预测器；
其中训练器已经接收了大量的先期隧洞开挖岩石数据以及各类地表岩石数据以及国内油田及煤田的钻井岩性数据，且这些数据均存于数据存储中心，训练器可以不断从数据存储中心获得新的数据开展训练；
训练器接收来自元素分析模块以及矿物定量模块的信息，通过与已有数据对比和训练，最终可按照原理一和原理二进行分级；
训练器接收显微图像模块信息，进行图像学习，提取数据，同样是与存储***中已有的数据不断进行对比，获取解理信息与晶体结构信息，依据原理三进行分级；
训练器最终结合三类分级按照预置的分类标准给出岩层抗风化能力的级别；
预测器将待检测的结果与数据存储中心中人工分析的各类岩样结果进行比较，通过训练器训练出的模型判断岩石中长石与抗风化能力的对应关系类，作为辅助预测。
数据采集***在TBM任何停机期间进行对掌子面进行数据采集，全自动高清摄像头对掌子面进行扫描，使用激光破岩设备对掌子面开展随机取块样，小型冲击钻机取粉末样，通过搭载的X射线分析设备及对应的数据解译***进行岩层中各类化学元素初步识别，但由于长石发育有大量的类质同象问题，从而需要电子探针***进行元素化合物或者矿物的定量分析。
显微图像模块是指依据长石的显微特性不同，如：正长石两组节理呈90°相交，斜长石不呈90°，此外，对其晶体形状进行识别(自形、半自形、它形)，干涉色识别(正长石干涉色为一级灰—灰白，斜长石干涉色一级黄，平行消光)，突起识别(正长石为负突起、斜长石为正突起)。
原理一：矿物的结晶温度越低其抗风化能力便越强，不同的长石其结晶顺序有明显的先后关系，因此钾长石的抗风化能力高于斜长石(即正长石比斜长石的抗风化能力强)，或碱性长石抗风化能力大于斜长石，而在斜长石中则以酸性斜长石大于中性斜长石大于基性斜长石，综上可知，按照不同长石的种类提供判别标准来看，正长石(钾长石)>酸性斜长石(钠长石、奥长石)>中性斜长石(中长石)>基性斜长石(拉长石、培长石、钙长石)。通过对比其元素含量，我们提供一种更为简单的划分，既当长石中仅含有K元素时，其抗风化能力最强，Na元素其次，仅含有Ca元素时其抗风化能力最差，当同时含有Na和Ca元素时，其抗风化能力随Na元素含量的增多而增强。
原理二：长石在碎屑岩石的碎屑中所占的比重，在碎屑岩中，长石本是原岩经过风化后的产物，这说明其本身具有较强的抗风化能力，因此，其在岩石中的含量越高，其抗风化能力就越强。
原理三：晶体结构，矿物在结晶时如果有较为充足的结晶时间和生长空间，其便会按照其自身具有的晶体结构生长为固定的形状，因此，当矿物结晶后保持了自身的晶体结构与形状，则称为自形晶体；保留的大部分晶体形状，则称为半自形晶体；完全丧失了其自身形状，则称为它形晶体，而矿物的晶体形状保存的越完好则说明其更加稳定，其抗风化能力也越高。
依据上述原理，并结合岩石圈中岩石的基本特征提出如下判别等级：若碎屑岩中的长石类型仅为钾长石—1级；钾长石>斜长石—2级；钾长石<斜长石—3级；仅为斜长石—4级。
若长石在碎屑岩占碎屑含量超过50％—1级；15％-50％—2级；5％-15％—3级；<5％-4级。
长石的晶体结构，自形含量>半自形+它形—1级；自形含量+半自形>它形—2级；自形含量≈半自形+它形—3级；自形含量+半自形<它形—4级。
按上述三个标准，最终定出长石特性对岩层风化程度的最后判断级别：至少存在一个1级和2级或2个2级则抗风化能力为优，仅存在1个1级或2级则抗风化能力为中，不存在任何一个1级或2级则抗风化能力差。
