摘要
通过裂土地区挡墙土压力的实测、模型试验、现有设计方法和既有挡墙使用情况的调查研究，搞清了裂土地区挡墙上的土压力分布。据此，提出了一种实用的，考虑了裂土膨胀作用在墙背上的土压力分布图形的设计计算方法。为了降低膨胀压力，推荐了裂土地区挡墙墙背缓冲层设置的合理厚度和配置。
The distribution of lateral swelling pressure caused by expansive soils behind retaining walls is recognized through the observations of earth pressures,the modeI tests,the investigations of current design Methods and the situations of the existing retaining walls.Thus,a practical design and computation method of retaining walls considering the distribution graph of lateral swelling pressures on the retaining wall is given。In order to reduce lateral swelling pressures,the reasonable thicknesses and the structure types of buffer laveresbetween retaining walls and expansive soils are recommended。
