Analysis of Influence Factors on Strength of Mudstone with Soft-Hard Alternant Strata in Nanning Basin
The mudstone is formed under the special environment with soft-hard alternant strata in Nanning Basin . The composition,engineering and mechanical properties have a certain complexity and specificity,so the parameters of the mudstone are discrete and variable by which the strength characteristics are influenced. According to the problem of the strength of mudstone,the influence factor is analysed on the strength of mudstone with soft-hard alternant strata in Nanning Basin through the composition, stress history, geological environment, water-rock interaction and disturbance, etc.. The analysis shows that in the final analysis the reduction of the mechanical properties of mudstone is due to structural damage, stress weakening and energy weakening.And the measures of improving the bearing capacity of mudstone are discussed from the test methods, construction control measures, in situ testing and engineering design.
