Abstract: The rock samples,which are collected from the first-stage project field of Funing port in Yunnan Province,are carried out the conventional triaxial compression test after the different numbers of drying and wetting cycles. The mechanical properties parameters variation rule of mudstone and sandstone under the water-rock interaction can be found through the measured rock mechanical properties regression analysis. The continuous damage mechanics approach,based on the elastic modulus,is applied to compare and analyze the deterioration characteristics of mudstone and sandstone. The strength between rock and rock mass has been obtained after engineering conversion of rock mechanic parameters by Hoek-Brown strength criterion. The changing characteristics of overhead sloping type wharf properties have been obtained during the water- rock interaction based on the finite element method.

Key words: water-rock interaction, mechanical properties, deterioration, overhead sloping type wharf, reservoir bank

摘要: 依托云南省富宁港一期工程,现场采集岩石试样,经过不同次数的干湿循环后作常规三轴压缩试验; 对实测岩 石力学性能参数进行回归分析,得到泥岩及砂岩在水岩相互作用下力学性能的变化规律; 基于岩石弹性模量,应用 连续介质损伤力学方法对比分析了泥岩及砂岩的损伤劣化特点; 应用Hoek-Brown 强度准则对岩石力学参数进行转 换得到岩体综合强度参数; 通过有限单元法得到不同次数的水岩相互作用下架空斜坡码头性能的变化特点。
