Deformation Mechanism and Design Countermeasures of Tunnel Portal in Volcanic Deposit Clay Stratum

Shortly after tunneling,problems such as primary-support through cracks and clearance infringement are found in the shallow-buried section of tunnel No.4 of the Jakarta-Bandung High Speed Railway(Jakarta-Bandung HSR),and orthogonal cracks can be found on the earth surface in front of the working face,which brings great challenges to the tunnel construction.In view of the above engineering problems,the sliding surface is speculated according to the geological and field conditions,and the impact of landslides is applied in the model in the form of external load.The paper uses the numerical simulation method to analyze and compare the impact of landslides on the tunnel structure and deformation,and puts forward the reinforcement measures.The conclusions of the studies are:(1)under the influence of heavy rainfall,the strength index of volcanic deposit clay stratum drops sharply,and meanwhile the multiple factors including tunnel excavation are liable to cause sliding of the front slope;(2)parallel landslide in front of the tunnel has a great impact on the tunnel,so setting-up of pre-reinforcement measures to control landslide shall be the focus of similar projects during design;(3)the deformation and stress of the tunnel structure can be significantly controlled for safe construction by strengthening the shallow-buried tunnel with pile foundation and longitudinal and transverse beam frames during landslide.

火山堆积黏土地层隧道洞口变形机理及设计对策

雅万高铁4号隧道在进洞后不久浅埋段出现初支贯穿裂缝、侵限等问题,同时掌子面前方地表出现正交裂缝,给隧道施工带来极大挑战。针对以上工程问题,根据地质及现场情况推测滑移面,将滑坡影响以外荷载形式施加在模型中,通过数值模拟的方法对比分析了滑坡对隧道结构及变形的影响,并提出加固措施。研究得出以下结论:(1)火山堆积黏土地层在强降雨的影响下导致强度指标急剧下降,同时隧道开挖等多重因素极易导致仰坡的滑移;(2)隧道前方出现平行滑坡时对隧道影响较大,在设计时设置预加固措施控制滑坡应为类似工程中的重点;(3)浅埋隧道在滑坡时采用桩基及纵横梁的框架加固后可显著控制隧道结构的变形及应力情况,达到安全施工的效果。
