快速准确地测量大型地下能源储库群容积，不仅是检验工程设计和施工建设成果科学合理性的一种方法，也是能源储运工程的基本要求和油库运行期间动态调控的基础。为了快速精确获取储库群容积和厘米级的高程-容积曲线，研发了基于断面的激光精细测量系统(LSMS)，建立了相应的数据处理方法。并成功将其应用到某地下能源储库的容积测量中，获得了厘米级的高程-容积曲线，通过回归计算，获得了容积真值，容积测量精度达到-0.06%，优于规范要求一个数量级。最后，结合全站仪和基站式三维激光扫描仪(TLS)的实验数据，对8个技术指标进行了对比分析，验证了激光精细测量系统及相应的数据处理方法的可行性和正确性。

Quickly and accurately measuring the volume of large underground energy storage caverns is not only a method to test the scientific rationality of engineering design and construction achievement, it is also the basic requirement for energy storage and transportation engineering and the foundation of the dynamic control during operation depot. In order to quickly and accurately obtain the storage caverns volume and the elevation-cumulative volume curve in centimeter level, a laser sophisticated measurement system (LSMS) based on cross section and the corresponding data processing method are developed. The method is successfully applied in the volume measurement of underground energy storage caverns and the elevation-cumulative volume curve in centimeter level is achieved. The true volume is estimated by regression analysis and the volume measurement accuracy can reach -0.06%, which is one order of magnitude better than the regulatory requirements. Combined with the experimental data of total station and terrestrial 3D laser scanner, eight technical specifications are comparatively analyzed. The feasibility and correctness of the laser sophisticated measurement system and the corresponding data processing algorithm are verified.
