Adaptive Drainage Decompression System Mitigates Liquefaction Uplift of Underground Utility Tunnels
https://orcid.org/http://orcid.org/0000-0002-5109-9210
Uplift is one of the main manifestations of seismic damage in lightweight underground utility tunnels. This paper proposed an adaptive drainage decompression system (ADS) that reduces the liquefaction uplift of the structure. The ADS consists of gravel piles, gravel diversion blind trenches, and relief wells. Using the finite difference program Flac3D to build the base model (BAC) and the adaptive drainage decompression system model. Using the Finn-Byrne constitutive model to account for the liquefaction properties of loosely saturated sands. The results of the two numerical models were then compared to analyze the development of excess pore water pressure, the deformation of the soil, and the uplift of the structure under dynamic loading. The results showed that the new adaptive drainage decompression system had excellent drainage properties and would effectively dissipate excess pore water pressure accumulated in vibrations. The maximum uplift value for the utility tunnel in the ADS model was reduced by 55.2% compared to the base model.
