Engineering Characteristics of Soft Ground Reinforced by Pre-Fabricated Band-Shaped Drain and Discharge Capacity

摘要

The well resistance and consolidation delay by smear zone are reviewed and a new theory is proposed. Based upon the proposed theory, a required discharge capacity is defined as neglecting well resistance. Almost of PBDs recently supplied in Japan are proved by the experiment to have discharge capacity over the required value. Since there is the characteristics of structure affect the discharge capacity, two models for confining conditions are examined to predict the difference in the capacity.
