Space monitoring method for deformation and displacement of existing underground structure in subway station construction
A space monitoring method for deformation and displacement of an existing underground structure in subway station construction combines a traditional drilling technology with an intelligent monitoring instrument, monitors same monitored points by using an inclinometer and a settlement meter to obtain deviation values and settlement values of the monitoring points, compares the deviation values and settlement values with reference points, obtains the absolute deviation value and the absolute settlement value of each monitoring point, simulates the space measurement track of the inclinometer and the settlement meter, namely the three-dimensional space track of a detection hole, according to the absolute deviation values and the absolute settlement values, and fits the outer contour of the existing structure according to the three-dimensional space track of the detection holes of the plurality of detection sections, so that the monitoring precision is improved. According to the method, the influence of the construction of the newly-built station on the existing structure can be predicted in the actual construction, the dangerous area in the construction is further determined, the protection scheme is formulated in advance, and engineering accidents are avoided. The method not only can be applied to detection of an existing tunnel, but also is suitable for stations and other large-burial-depth existing structures.
一种地铁车站施工对既有地下结构变形变位的空间监测方法，该方法是将传统的钻探技术与智能监测仪器相结合，通过使用测斜仪与沉降仪对同一监测点进行监测，得到各监测点的偏移值与沉降值，并与参考点进行对比，得到各监测点的绝对偏移值与绝对沉降值，根据绝对偏移值及绝对沉降值模拟出测斜仪与沉降仪的空间测量轨迹，即探测孔的三维空间轨迹，并根据多个探测断面探测孔的三维空间轨迹拟合既有结构的外轮廓，提高监测精度。本发明在实际施工中能实现预测新建车站施工对既有结构物的影响，进而确定施工中的危险区域，提前制定防护方案，避免工程事故发生。本发明不仅可以应用在既有隧道的探测上，也适用于车站及其他大埋深的既有结构。
