Research on the Collapse Coefficient of Collapsible Loess under Unloading [PDF]
Advances in Civil Engineering, 2021 In the geogenetic overburden excavation of underground space projects (such as comprehensive pipe corridors or subways), the foundation stress is in an unloading state. The effect(s) from the unloading on the coefficient of subsidence in the loess area should be considered.

In-situ evaluation of collapsible loess through time-domain reflectometry
Yantu gongcheng xuebao, 2022 It is urgent to propose a new technique for the in-situ evaluation of collapsible loess, as the existing methods are time- and cost-consuming, and may lead to inevitable sampling disturbance.
