华南沿海地区丘陵较多,地势起伏,沿海养殖设施普遍为浅基础建设.在水产养殖技术方面,现有研究主要集中在养殖技术上,而有针对、有系统的研究结构性土体的研究方法还不多,在试验方面多采用人工制备结构性土体的研究方法,因此开展这方面的计算机模型分析和试验研究,对各种不同的处理方式进行效果分析,找出适合水产养殖设施改造的方式,可以为今后水产养殖设施如池塘改造等项目节省资金和施工时间.破损力学的核心思想是将结构性岩土材料抽象成由胶结强的结构体(弹脆性元)和无胶结的破碎体(弹塑性元)组成的二元介质,是一种建立在准连续介质概念基础上对岩土材料进行宏观分析的力学理论.采用数值模拟的方法进行模拟土体三轴试验,研究土中胶结强度对土体破坏模式、应力爬坡及剪切带的影响,以期为该问题的研究提供新的借鉴.

The South China coastal area is rugged with hills,therefore,the aquaculture facilities are usually constructed on shallow foundation.The current researches on aquaculture mainly focus on technology but not on systematic studies of structurial soil.Since artificial structural soil is often used in tests,it is necessary to carry out the research on numerical simulation method,analyze the effects of different treatments and determine the appropriate reconstruction approach for aquaculture facilities,so as to save time and money for the future projects such as pond reconstruction,et al.Damage mechanics is a mechanical theory of macro analysis on geomaterials based on the concept of quasicontinuous medium; its core idea is that geomaterials are conceptualized as binary medium consisting of bonded blocks and weakened cells which are idealized as elastic-brittle element and hardening elastic-plastic element respectively.With numerical simulation method,the paper simulated a triaxial test of soil,investigated the influence of the cementing strength on destruction pattern stress hill climbing as well as the shear zone of the soil,which provided references for the matter concerned.
