江西理工大学硕士学位论文 江西理工大学硕士学位论文 Abstract 万方数据 万方数据 reinforcement depth calculated is 0.4 to 0.6 under the effect of the impact energy, so the valid reinforcement depth may be estimated by settlement amount of soil, and the research results have certain referenced value. (5) The influence scope of soil’s density is a ellipsoid sphere under impact energy; based on the change of the soil’s density and the relationship between the settlement amount and the reinforcement depth, the theoretical formula of reinforcement depth and width is deduced. Results of this study enriches the impact reinforcement theory of red sandstone soil and have a certain reference value for the further study to red sandstone soil, and some guidance is provided to engineering practice of similar foundation treatment. Key words: single impact energy; red sandstone soil; effect; displacement characteristics; reinforcement range III 江西理工大学硕士学位论文 江西理工大学硕士学位论文 目录 目 录 摘 要........................................................................................................................I Abstract......................................................................................................................II 目 录 ......................................................................................................................
