本研究提出了一种新的干预方法的拱门和拱顶的文艺复兴时期的工厂在圣多明各德奥里韦拉学院（世纪），使用三维软件激光雷达技术，验证执行过程中的工程研究不同的收费状态和结构行为。本文件旨在解释监测建筑遗产中结构维修干预的工作方法，特别是在拱顶之间的前、八字形和腹股沟拱结构上更换传统单向木托梁框架板的情况下。这涉及两类数据的汇编和处理：一方面，分析干预措施在其不同阶段所处的不同荷载状态：初始阶段、拆除传统建筑的不同层以及用新的结构系统取代;另一方面，由摄影测量技术提供的图形信息，用于确定结构元件的尺寸和空间位置，历史性地解决了这种文艺复兴式解决方案中建筑空间的覆盖问题。不同的层和拆除的材料已经通过分析它们的结构配置、厚度和构成初始建筑系统一部分的元件的尺寸以及它们自身的重量进行了验证。此外，修复项目中使用的新建筑系统产生了与现有系统相似的荷载状态。在研究过程中使用的激光雷达技术提供了在施工干预的不同状态下研究的拱和拱顶的空间位置的图形数据。通过将食堂的固定点（被认为是不可变的和无限刚性的）作为参考来分析所获得的点云，并且比较初始和最终状态的坐标。结果表明，两个位置之间的变化很小，这证明了所使用的施工方法和结构安全的复杂性。这种应用于传统建筑中拱门和拱顶的方法保证了对过程中产生的运动的控制和记录。
This research presents a new intervention methodology on arches and vaults of a Renaissance factory in the Colegio Santo Domingo de Orihuela (16th century) using 3D software LIDAR technology that verifies the execution process of the works studying the different charges states and structure behavior. This document aims to explain a working methodology in the monitoring of structural repair interventions in the architectural heritage, in the specific case of the replacement of traditional one-way timber joist frame slabs on structures of former, splay and groin arches between vaults. This involves the compilation and processing of two types of data: on the one hand, the analysis of the different load states to which the intervention is exposed in its different phases: initial, dismantling of the different layers of traditional construction and replacement by the new structural system; and, on the other hand, the graphic information provided by the photogrammetry techniques used to dimension and define the spatial position of the structural elements that have historically resolved the covering of the architectural space in this type of Renaissance solution. The different layers and demolished materials have been verified by analysing their constructive disposition, thicknesses, and dimensions of the elements that formed part of the initial construction system and their own weights. In addition, the new construction systems used in the restoration project generate a state of loads similar to the existing one. The LIDAR technology used in the research process provides graphic data of the spatial position of the arches and vaults studied in the different states of the construction intervention. The point clouds obtained are analysed by taking as reference fixed points (considered unalterable and infinitely rigid) of the refectory and the coordinates of the initial and final states are compared. The results show minimal variations between the two positions, which justifies the goodness of the construction methods used and the structural safety obtained in the complex. This methodology applied to arches and vaults in heritage architecture guarantees the control and recording of the movements produced in the process.
