摘要
在2008年汶川MS8.0地震地表破裂带科学考察中,利用全站仪、差分GPS和三维激光扫描仪等高精度测量技术对同震变形造成的微地貌进行测量,及时记录了地表同震变形现象的丰富信息,为相关的定量分析提供了有效保障。文中探讨了选择不同测量技术在微地貌测量中的应用特点和组合优势,结合测量实例分析了三维激光扫描仪在完整记录和有效分析地震地表破裂带信息方面的优势及其限制条件,并进一步讨论了上述测量方法的应用前景。
In the scientific investigation on the Ms8.0 Wenchuan earthquake, different high-precision measuring instruments, such as electronic total station, GPS RTK,3D laser scanner, etc. were used widely to survey the landscape of co-seismic surface ruptures, and a wealth of information with the earthquake deformation were recorded timely, which ensured the quantitative analysis of related data. In this paper,we explored the characteristics of different means used in the micro-geomorphology survey and analyzed the advantages of different portfolios of the above-mentioned methods. Then, focusing on the examples, we discussed the advantages and limitations of three-dimensional laser scanner in recording and analyzing the information of seismic surface ruptures. Also we gave the prospects of the methods＇ application.
