Effects of water environment on the erodibility and microstructure of remolded loess by the Mountain Excavation and City Construction (MECC) project in Lanzhou City, China

The economy of Lanzhou City has experienced rapid growth, yet it faces significant spatial constraints. To address this issue, the local government initiated the Mountain Excavation and City Construction (MECC) project. However, the remolded loess fill utilized in the MECC project is susceptible to erosion upon exposure to water, thereby compromising the stability of the fill foundation and potentially causing structural damage to buildings. My data shows all the data we derived using NMR as well as SEM, among others: Variations in the T2 distribution of remolded loess; Pore size distribution for the different soil samples before and after seepage; Directionality of the pores; Pore circularity characteristics; Particle abundance in samples before and after seepage; Particle circularity characteristics and Directionality of particles.
