摘　　要：根据海涂土壤特性设计了不同形状参数的测板 ,配装于 SY- 1型静载式水田土壤承压仪 ,在进行海涂土壤承压特性研究中取得了较理想的效果。实测与分析发现 ,Bekker模型及其修正模型均不能适用于海涂土壤。提出了能适用于海涂土壤的承压模型 。In accordance with the characteristics of coastal shoaly land, authors designed several measuring dishes with different shapes and sizes. These dishes were disposed to a SY 1 dead load paddy field soil pressure instrument to study soil pressure sinkage characteristics on coastal shoaly land in Zhejiang. With the help of those apparatus, a good effect was found in tests. Test result and analysis showed that Bekker model and its revised version do not fit with coastal shoal land and, therefore, a new soil pressure sinkage model more applicable for coastal shoaly land was put forward. Moreover an important theoretical basis developed for the design of coastal shoaly land machinery.
