Geofluids, Volume 2022, Issue 1, 2022., 2022 A new method of replacing soft soil with lightweight foam concrete (lightweight foam concrete replacement method, LFCRM) is carried out to treat deep soft foundation under the low‐filled embankment. Two‐dimensional models with different thicknesses of replacement are established by the finite element platform (MIDAS/GTS).

Advances in Materials Science and Engineering, Volume 2022, Issue 1, 2022., 2022 The strength of the roadbed composed of soft rock decreases following water immersion. Cement slurry is mixed with a soft rock to strengthen the soft rock roadbed to address this problem. The uniaxial compressive strength was determined, and the triaxial compression tests were conducted to analyze muddy sandstones mixed with different amounts of the ...
