Abstract: A method for reinforcing soft ground by post-grouting combined with pressurized vacuum preloading is proposed, by pre-burying prefabricated vertical drains and air-boosted pipes in granular material piles, and the air-boosted pipes are used as grouting pipes to reduce the number of times of piling, which not only improves the construction efficiency, but also reduces the structural disturbance of the soil and the influence of smear effect, thus reducing the impact on the radial permeability and the radial consolidation coefficients. The method does not use geotextile bags for granular materials, which can avoid the problem of forming a localized clogging area around the geotextile bags, and the method not only improves the efficiency of vacuum transfer in a pre-consolidation stage, but also improves the grouting effect in the later stage, effectively enhances the strength of soft soil and makes granular material piles and the surrounding soil form composite ground.

Abstract: A multi-objective optimization method and system for a master production plan of casting parallel workshops belonging to a casting, producing, and scheduling fields are provided. In the method and the system, discrete coding is adopted, and parallel scheduling information is directly converted into discrete particles. Through crossing and mutation of each particle together with non-dominated particles in a global optimal solution set and individual optimal solution sets, a quick search of a solution space is completed. Congestion distances of non-dominated individuals in the solution space are calculated, sorting is performed according to congestion, and a new population is generated to allow the solutions to be uniformly distributed.
