Abstract: Deformation is one of the most significant forms to reflect slope stability. The existing slope deformation monitoring is mainly completed by setting surface deformation or internal deformation monitoring items independently, without integrating the surface deformation with internal deformation, that leads to complex measurement process, large cumulative error and manual data correction. Using the surface GNSS technology and the internal MEMS monitoring technology, combined with the new embedded system, a surface and internal deformation integrated and automatic monitoring device is developed, which can achieve truly all- round and effective monitoring, mutual check of data, and more accurate and reliable understanding of the actual operation of the slope.

Key words: slope deformation, GNSS, MEMS, integrated automatic monitoring device

摘要： 边坡变形是反映边坡稳定性的最显著形式。现有的边坡变形监测设置单一的内部变形或表面变形监测 项目，没有将表面变形和内部变形有机结合起来，存在测量过程复杂、累积误差大、数据修正需依靠人工等不足。 采用表面GNSS技术和内部多轴变形监测技术，结合新型嵌入式系统，开发了一款表面-内部变形一体化自动监测 装置，可达到真正全方位的有效监测，内外变形数据相互校核，可更加准确可靠地掌握边坡实际运行状况。
