摘要:基于TM50测量机器人,以重庆市沙坪坝区嘉陵江畔某悬挑式危岩体为例,提出了一种非接触式结构面产状测量方法,并阐述了其测量技术原理和数学处理方法,以TM50 测量机器人安置点为原点,以磁北方向为x轴正方向,建立右手空间笛卡尔直角坐标系;利用空间向量和几何投影关系定量描述待测结构面倾斜状态,计算出结构面的倾角、倾向和走向.针对非接触式测量所得数据对气象及周期等方面提出了修正方法。将所测得的数据在Sketchup软件中进行模型建立,并将建立的模型与数字影像进行比较。通过比较可知,从而实现远距离或难以接触的结构面产状测量,进而证明TM50测量机器人在岩体边坡控制测量和模型建立中的可行性、非接触式测量技术在建立边坡立体模型的准确性以及获取结构面产状信息的可靠性。

The measurement modeling and stability of suspension critical rock mass based on non-contact measurement technology is proposed
Abstract:Based on the TM50 measuring robot, a kind of non - contact structural surface measurement is proposed in the Jialing River of Chongqing as an example. The principle of measures and mathematical method are described. The inclination of the structural plane is calculated by using the space vector and geometric projection relationship to describe the tilting state of the structural plane to be measured quantitatively. As for the direction, aiming at the weather and period of non - contact measurement data, a modified method is proposed. The measured data is modeled in the Sketchup software and the established model is compared to the digital image. The feasibility of the TM50 measurement robot in the rock slope control and the establishment of the model is proved by the comparison, and the non-contact measurement technique is used to establish the three-dimensional model of the slope. Accuracy and reliability of the information obtained from the structural surface.
Keywords: Potential unstable rock mass Occurrence measurement Non-contact measurement Technical principle Mathematical method Establishment of model.
