Prediction model and application of three-dimensional ground surface settlement induced by tunnel excavation considering time effect

open access: yes矿业科学学报, 2019
It is difficult to consider the change of settlement along with time by using stochastic medium theory in the settlement prediction process in subway construction. A new settlement-time model is proposed.

Deformation characteristics of ground with voids induced by shallow metro tunnelling

open access: yesYantu gongcheng xuebao, 2019
The existence of the ground voids makes the ground conditions around the tunnel more complex, which may increase the ground surface settlement and even induce collapse during shallow metro tunneling.

The effect of suction on ground surface settlement for a tunnel [PDF]

open access: yesE3S Web of Conferences, 2019
This paper addresses the physical modelling of a tunnel for saturated and unsaturated sand as well as tests in dry condition. A series of tests were conducted for a 50 mm diameter tunnel buried 25 mm into a poorly graded fine sand under different normal stresses: 0.78, 1.56, 2.34 and 3.31 kPa.

Horizontal Wall Movement and Ground Surface Settlement Analysis of Braced Excavation Based on Support Spacing

open access: yesUKaRsT, 2021
Lateral supports, including walls and bracing systems on deep excavation, are generally required to prevent excessive horizontal wall movement and ground surface settlement which can cause damage to the excavation construction itself and adjacent ...
