Abstract

Cisumdawu Tunnel is a twin tunnel 472 m long located in Sumedang. Twin tunnel construction can cause additional ground settlement and tunnel deformation. The tunnel construction method used is the New Austrian Tunneling Method (NATM) and umbrella grouting protection system. The principle of NATM is to maximize surrounding soil capacity to support its weight and balance the stresses around the tunnel. Investigation of tunnel deformation is important to know tunnel structure behavior and avoid possible failure. This research aims to know tunnel deformation and the effect of twin tunnel construction on the deformation and ground settlement. The data used such as tunnel geometry, monitoring data, pressuremeter test, and the drilling test. The 3D analysis will be performed for a single tunnel and twin tunnel using Midas GTS-NX, and monitoring data will be used for verification analysis. The 3D FEM help to model the soil condition and construction stage according to the actual condition. The analysis results show the maximum tunnel deformation that occurs from the beginning of the tunnel construction is 12.64cm. If the deformation starts to be calculated following the monitoring reading time, after the excavation at the monitoring point, the maximum deformation of the analysis results is 3.3&4.4cm, where the monitoring shows maximum deformation of 3.3&4.3cm. Through the results, it can be said that the analysis using 3D FEM with pressuremeter test parameter represents actual conditions. Twin tunnel construction side-by-side increases ground settlement and lateral tunnel deformation significantly. Hence, it shows that tunnel analysis using 3D FEM recommends for future investigation of tunnel deformation.

Abstract

Soil  as  a  subgrade  foundation  under  embankment  construction often  creates  problems  in  terms  of  stability  and  settlement. Therefore, it needs improvement by using preloading embankment. This article presents the investigation of pile behavior towards two scenarios  of  abutment  construction  using  Plaxis  3D,  a  three- dimensional  finite  element  program.  The  use  of  two  scenarios  of analysis was Method A. The abutment construction phase conduct without using a preloading embankment, and Method B, where a preloading  embankment  constructs  before  the  abutment construction.  The  case  study  location  at  the  Lembak  bridge. Compare  the  analysis  results  with  the  measured  data.  Results showed that Method A and Method B's pile deflection yielded four times  and  one  point  six  times  larger  than  the  measure  data, respectively.  Hence,  it  indicates  that  Method  B  recommends  for future construction of bridge abutment.
