Research On Some Aspects In Workout Of Technological Regulation For Projects In Mudstone Area

With the economic development of Guangxi, more and more projects have the function with mudstone directly. Because people lack enough understanding of the nature of mudstone, and have not appropriate standard to refer, they don't know how to process this special rock, as a result of that, many questions appear during the construction and operation of engineering project, and has created heavy losses.Based on this, the paper proposed several key contents that should be considered during the making of the rule that involving mudstone engineering: The distribution of mudstone, the differentiation and classification of mudstone, the bearing capacity of mudstone foundation, the mudstone slope, rock-socketed pile in mudstone, deformation of foundation pit supporting structure inbedded in mudstone, the underground chamber in mudstone and so on.Then the characteristics and engineering property are summarized and distributing charts are protracted, and the formation lists are descripted. Next, differentiation and classification of mudstone are thoroughly analyzed and summarized, and a more scientific and applicable method is advanced.Summaried the disease type of mudstone slope, has analyzed characteristic and the reason of the mudstone landslide; several questions of stability analyzes are analyzed, put forward some proposal for remedy measure.In the analysis of rock-socked pile, the definition of rocked-pile, the post-grouting technology, the largest and best rock-socked depth are studied, the deficiency of the domestic code is analyzed, and some suggestions are raised.
