岩土体深层水平位移测试过程中经常面临更换测斜仪的问题,个别情况会产生测试数据不连续的测试间断现象,常规算法不能计算测试间断期的位移增量。依据滑动式测斜仪的测试原理和应用条件提出了新的测斜数据算法,即相邻测量的逐点增量对接法和单次测量的绝对位移法。相邻测量的逐点增量对接法是根据测试间断期先后2次来自不同仪器的测试数据来计算间断期的位移增量,原理简单,操作方便;单次测量的绝对位移法是仅根据间断期后单次测量数据算得间断期末不同深度的累计位移,无需间断期前的测量数据。工程实例应用表明:2种方法均能实现测试间断期的位移增量求解,二者的计算结果一致。
In the process of deep horizontal displacement test of rock and soil, the problem of changing inclinometer is often encountered. In some cases, there will be intermittent test discontinuities. Conventional algorithms can not calculate the incremental displacements during test discontinuities. According to the test principle and application conditions of sliding inclinometer, a new algorithm of incline data is proposed, that is, the absolute displacement method of the point-by-point incremental docking method and the single measurement of the adjacent measurement. Adjacency measurement point by point incremental docking method is based on the test interval of 2 successively from the test data from different instruments to calculate the displacement of the incremental displacement, the principle is simple, easy to operate; single measurement of the absolute displacement method is based only on the intermittent The single measurement data after the period is calculated as the cumulative displacement of different depths at the end of the discontinuity without the need of the measurement data before the discontinuity period. The application of the engineering example shows that both methods can solve the displacement increment of the test discontinuity, and the calculation results of the two methods are the same.
