摘要岩体结构面的特征情况是任何一项岩体工程研究必须经历的一个方面，所以充分了解岩体中结构面的分布情况在工程实际中显得格外重要。 随着计算机技术、测量技术的发展，以及现代化施工的需求，基于数字近景摄影测量技术快速采集岩体结构面信息的方法，为岩体结构面信息的快速采集开辟新的途径，展现出了广阔的应用前景。 本文的目的是通过研究，掌握结构面摄影测量的方法，并且利用拍摄的图片及量测等资料，对岩体结构面参数进行较为系统的识别分析。 本文首先介绍了数字近景摄影测量的定义、发展以及在岩体结构面研究中的作用，对数字近景摄影测量技术进行充分的总结；然后较系统地阐述了岩体结构面信息获取中数字近景摄影技术的原理和方法，主要包括近景摄影测量理论、摄影要求、控制点坐标的获取、特征匹配原理以及岩体结构面裂隙参数的解译。最后，本文以一个应用实例详细说明了数字近景摄影测量在岩体结构面信息获取中的计算过程。通过计算分析，最终得到了结构面的裂隙迹线图，但实验中的数据处理精度和方法有待进一步提高和完善。61114

Title Application of digital close-range photogrammetry in rock engineering
Abstract Fractures of rock mass structural plane are necessary for any one rock mass engineering study, so it is particularly important to fully understand the distribution of structure plane of the rock mass in engineering practice. With the development of computer and measurement technology and the needs of modern construction, measurement techniques based on digital close range photogrammetry which could fast collect the information of rock mass structure plane provides a new approach to collecting information of rock mass structural plane, and shows a broad application prospects. The purpose of this thesis is to master the methods of structural plane photogrammetry, and makes a systematic analyze of the parameters of rock mass structural plane by using of images and information of measurement. This thesis first introduces the definition and development of the digital close-range photogrammetry and the role of research in rock mass structural plane. and make a full summary of the digital close-range photography measurement technology; And then this thesis states systematically the principle and method of the digital close-range photogrammetry technology, mainly including the close-range photogrammetry theory, photography requirements, acquisition of control-point coordinates , principle of feature matching, and interpretation of the rock mass structural plane fracture parameter. Finally, based on an application example this thesis details the calculation process of digital close-range photogrammetry in the rock mass structural plane information acquisition. Through and analysis, it finally obtains the structure fracture traces diagram below, but the experimental method and precision of data remain to be improved .
