Lateral earth pressure and lateral subgrade reaction of braceless earth retaining walls in Kanto Loam ground

Lateral pressure and lateral subgrade reaction for designing earth retaining in Kanto loam ground were examined using field measurement, full scale horizontal load test, and analysis. 1. At earth retaining using soldier piles and lagging method, by enlarging intensity of cement bentonite enough to ground, cement bentonite carries out an action united with a soldier pile, and contributes to the increase in horizontal resistance. 2. Coefficient of lateral earth pressure counted backward from the actual measurement of displacement of earth retaining walls of 8 sites (16 points) in Kanto loam ground was distributed from 0.011 to 0.129.
