相较于传统沉船整体打捞工法,矩形曲线顶管底幕法具有施工周期短和对沉船损害小的优势.为了在沉船打捞过程中实时获取曲线顶管底幕法主要构件(顶梁、端板和管节)的位移,引入光频域反射计(optical frequency domain reflectometer,OFDR)...相较于传统沉船整体打捞工法,矩形曲线顶管底幕法具有施工周期短和对沉船损害小的优势.为了在沉船打捞过程中实时获取曲线顶管底幕法主要构件(顶梁、端板和管节)的位移,引入光频域反射计(optical frequency domain reflectometer,OFDR)光纤传感技术,推导了基于光纤监测应变的位移计算式.对顶梁、端板和管节分别布设光纤进行应变监测并计算其在施工过程中的位移.研究结果表明:在顶梁-端板框架沉放过程中,由于两侧顶梁受力不均,其沿竖向的变形模式有所差异,而端板所受影响较小,侧向位移最大值不超过0.3mm;在管节推进过程中,侧向位移和径向收敛位移趋势整体相似,均未超过1mm,端板和顶梁变形小于沉放阶段.该研究成果以期为光纤传感技术在地下工程结构物应变和位移监测的应用中提供技术基础和案例参考.展开更多
