变形隧洞围岩收敛监测及回归分析

Convergence Monitoring and Regression Analysis for Deformed Tunnel

不良地质段隧道围岩变形大、变化快、事故具有突发性的特点,积极采取现场围岩变形量测,及时了解变形量、变形时间及变化规律是非常有益的。这样,施工开挖与支护衬砌就有了较充分的科学依据,可以减少施工中人为主观因素的影响。

The surrounding rock of the tunnel section with poor geological condition is featured by large deformation,sudden change and abrupt accident.Therefore,it is beneficial to adopt on-site surrounding rock deformation measurement to understand the deformation amount,deformation time and change law.In this way,the construction excavation and support measures have a sufficient scientific basis,which can reduce the influence of human subjective factors during construction.
