Practice of Grouting Reinforcement for Soft Ground Foundation

Abstract:

According to the comprehensive analysis on the field situation and economic factors, necessary reinforcement measures were taken for a primary school playground to control the settlement by grouting reinforcement in backfilling layer in order to improve the mechanical properties of rock soil for the integrity restoration. In the field experiment and settlement monitoring for a year, the maximum settlement was only 15cm, and the settlement-time curve showed that the settlement is stable, which proved reinforcement effect satisfied the engineering requirement.
