实际的激光测量中往往无法综合考虑激光测量参数的影响，导致激光测量参数设计不合理，测量数据质量不高。该文基于激光测量参数的影响特点，综合考虑多个影响因素，建立了激光测量参数的控制标准和地下能源储库测量参数设计模型，并对具体的测量参数进行了流程设计。结合实际的地下能源储库的工程参数及工程要求，实现了固定式和移动式激光测量方法的测量模拟和参数设计，并采用设计的测量参数进行了地下能源储库的激光测量，得到了较高质量的测量数据。结果表明：激光测量模拟与参数设计方法是一种有效地满足复杂工程应用和测量要求的参数优化设计工具。
Laser survey parameters are difficult to select due to the effects of different factors on the laser measurements. The characteristics of laser survey parameters are used here to define a design criterion and a design model for the laser survey parameters. The storage cavern dimensions and application-dependent parameters were used on a laser survey simulation of an underground storage cavern based on the design model to identify the design parameters for an in-situ laser survey of an underground storage cavern. The results show that the laser survey simulation and parameter design are an efficient tool for studying the survey parameters to optimize the various tasks in the planning stage.
