Analysis on the Reinforcement Effect of Dynamic Compaction Replacement Method in Foundation Treatment of Civil and Industrial Buildings
摘要
Abstract
Weak foundation treatment is a key link in industrial and civil construction projects.In order to explore the reinforcing effect of dynamic compaction replacement method in complex geological conditions,in view of the foundation conditions of the industrial and civil buildings,the paper uses dynamic compaction replacement method for reinforcement design.The method uses a 15-ton rammer with a 16.7 meters drop distance to generate 2 500 kN·m tamping energy,sets a 4.5 meters tamping point spacing,and selects graded gravel as the replacement material to implement the layered backfill process.The experiment shows that the bearing capacity of the treated foundation reaches 195.28 kPa,the compression modulus increases by 83.33%,and the pore ratio decreases by 27.83%.And the settlement was reduced by 37.99%compared with other methods,and the foundation bearing capacity was improved by 41.46%.The results show that the dynamic compaction replacement method can efficiently solve the stability problem of weak foundation at high water level through the synergistic effect of vertical reinforcement of crushed stone pier and soil compacting,and provide economical and efficient treatment plan for similar projects.关键词
