172 Study on the Statistic Damage Model of Joint Rock in Railway Roadbed Slope Quality Evaluation Available to Purchase

Rockmass structure has a very important dominated function for stability of railway roadbed slope. Rockmass structure is principal composed of a large number of developing hard constructional surface which is smallish, spiccato, stochastic distributing. According to statistical analysis of locale project rockmass joint, rockmass structure subarea of railway roadbed slope is made. Research method of statistic damage model is used to calculate damage tensor quantity of each of rockmass structure subareas of railway roadbed slope. The analysis model which uses the biggest principal damage value to evaluate quality of construction rockmass is set up and used in practice.
