چکیده
Abstract Upward ( phase i ) pipe jacking project of hangzhou water intake is near existing bridge foundation and operating tunnel. In order to investigate the influence construction process on structures, Plaxis 2D finite element software was used simulate horizontal vertical displacement structures caused by construction. The calculation results show that: pile nonlinear distribution. There a bending point in foundation. maximum minimum are 0.71 mm and-0.84 mm, respectively. settlement only 0.29 mm. sidewall tunnel structure distributed, relatively large, but 0.13 deformation mainly uplift deformation, obvious, extreme value 0.09 Thus, impact bridges tunnels very limited. research great significance safety evaluation engineering

15 صفحه اولAssessment of Subsurface Explosion caused by Tunnel Construction in Urban Areas
Nowadays, tunneling in urban areas is a common activity for a variety of transportations such as subways, water supply, lifelines andsewers that may require blast operations. The characteristics of stress waves of the blast are quite different from earthquake waves. The blast waves are usually of high frequency content, short duration, equality of amplitudes in horizontal and vertical direction...
متن کاملNumerical simulation of water entry of tunnel cross section with different deadrise angles and tunnel radiuses
This study deals with the numerical modeling of symmetrical water entry of tunneled sections. In this study, firstly, the water entry problem of a wedge section without tunnel in four different deadrise angles was numerically modeled. The obtained results related to the pressure distribution on these sections and the maximum pressure have been compared with the experiment results. In the next s...
