Serial no. | Monitoring point no. | xi | yi | zi | Remarks |
|---|---|---|---|---|---|
1 | 2341761 | 4.90407 | 9.66302 | 50.2488 | The monitoring points numbered from 1 to 8 are the monitoring points common to the three models, and the numbering increases from the smallest to the largest as the distance from the palm surface increases. The monitoring points numbered 9 and 10 are the additional monitoring points on the upper platform, and the numbering increases from the smallest to the largest as the distance increases from the upper platform palm surface |
