Study On Budget Cost And Budget Quota Of Dynamic Compaction Foundation

Method of the dynamic consolidation foundation treatment have many advantages, the construction technology of it is so simple, and its cost is so low. So, the dynamic compaction method has been widely used at home and abroad. But there is a problem that the budget quota of dynamic compaction ground treatment in domestic corresponding is not yet perfect at present which gives inconvenience to the engineering cost management of the dynamic compaction ground treatment.In this paper, compared the dynamic compaction method with other foundation treatment methods in the field of project cost, and analyzed their project cost. This paper analyzes the budget quota of dynamic compaction method in Tianjin, Guangdong and Jiangxi province. Combined with the engineering practice of dynamic compaction method in Jiangxi province to optimize the low and middle level budget quota, calculates and supplement the high level budget quota. At last get the main conclusions and results as following:1, The current dynamic compaction ground treatment budget closed each other in geographically, and lagging behind in the development of construction technology. The budget quota of dynamic compaction method in Tianjin province only lists the corresponding specific item which below the2000kn. M level, and the budget quota of dynamic compaction method in Guangdong and Jiangxi province also lists the corresponding specific item which below the4000kn. M level. No the corresponding specific item of6000kn. M level which is being used widely. Not to mention the corresponding specific item of18000kn. M level.2, Contrast the dynamic compaction budget quota in Jiangxi province and what in Tianjin province and what in Guangdong province. At the last gave a reference object for the dynamic compaction foundation treatment method. The budget quota of Guangdong is so clear and has high levels than it in the other province. So it can be used as a reference for the dynamic compaction budget quota’s optimization in other provinces and cities.3, Make a reference optimization for the dynamic compaction budget quota in the energy level of1000kn. M,2000kn. M,3000kn. M and4000kn. M, wich has a smaller Consumption than the dynamic compaction budget quota that is being used in Jiangxi province. In addition to this, the levels of the dynamic compaction budget quota is been increased too.4, Make the measure and give a reference supplement for the5000kn. M and6000kn. M energy level about the dynamic compaction budget quota in Jiangxi province.The result about the research of this paper has certain theoretical and practical significance to improve the dynamic compaction ground treatment method, and to rich the theory of the cost management of the dynamic compaction ground treatment.
