摘要
隧道是典型的隐蔽工程,为监测隧道桩基的受力状态,实现隧道结构的全生命周期监测安全评估,引进准分布式光纤光栅传感技术。提出基于分布式应变的桩基监测内力计算方法,通过明挖隧道的现场监测试验,根据监测数据计算得出桩基内力,验证了该监测计算方法的适用性和有效性。
Tunnel is a typical concealed project.In order to monitor the stress state of the tunnel pile foundation and realize the whole life monitoring and the safety evaluation of the tunnel structure,quasi-distributed fiber Bragg grating(FBG)sensing technology is introduced A calculation method for monitoring internal force of pile foundation based on distributed strain is proposed.And the internal force of pile foundation is calculated according to the monitoring data through the on-site monitoring test of cut-and-cover tunnel,which verifies the applicability and effectiveness of the monitoring calculation method.
