Title: Study on the Settlement Characteristics of Foam Concrete Widening Subgrade by Numerical Analysis
Abstract: Based on FLAC3Dthe numerical analysis model of bubble concrete widening subgrade was established,the subgrade settlement distribution low and development process in construction was studied,and the influences of excavation depth and excavation width tostress replacementeffect of foam concrete was analyzed. Research shows that: under the old acting alone,the maximum settlement occurred in the emban km ent center line; under the load of new and old subgrade,the new settlement at center line of subgrade is minimum,while the maximum occurs at the part of the new subgrade; the differential settlement decreases with the replacement depth and excavation width increases.
