内河航道齿坎式护岸结构分析及应用

Analysis and application of riverbank protection structure with notched sill in inland waterway

齿坎式护岸结构是一种新型挡墙结构,但目前齿坎式挡墙缺乏理论设计规范。在进行抗滑稳定性计算时仍按照无齿坎结构进行计算,把齿坎当成安全储备,造成断面设计的浪费。通过对齿坎式护岸结构的有限元计算,得出比较经济的护岸断面结构型式。

The riverbank protection structure with notched sill is a new type of retaining wall structure, but there is not yet theoretical design standard. The anti - slippery stabilization computation of tooth - ridge structure is always deferred to the no notched sill roles. The notched sill is just regarded as the margin of the safety, which leads to the waste of the structure. Based on the finite element calculation of the tooth - ridge structure, the economical structure pattern for riverbank protection is obtained.
