摘要
作用在黏土挡墙上的侧压力是影响其安全性的重要参数。为探究竖向荷载和增湿含水率对重塑黏土侧压力的影响,用K0固结仪对非饱和状态下的重塑黏土进行试验,测量增湿和固结过程中的侧压力。试验结果表明,即便竖向荷载较小、增湿程度不大,重塑黏土仍会表现出较大的侧压力,现有的土压力理论会低估作用在黏土挡墙上的侧压力。
The lateral pressure is an important parameter for the safety of the retaining wall with cohesive soil backfills.To explore the influence of the vertical load and increased water content on the lateral pressure of remolded cohesive soils,an unsaturated remolded cohesive soil was tested by using K0 consolidometer.Testing results indicate that lateral pressure of the remolded cohesive soil may be high,although the vertical load or increased water content are low.The results also show that the current earth pressure theory may underestimate the lateral pressure on retaining walls with cohesive soil backfills.
