【摘要】：強(qiáng)夯地基處理方法因施工技術(shù)簡(jiǎn)單，工程造價(jià)低廉而被國(guó)內(nèi)外廣泛應(yīng)用，但其預(yù)算定額尚不完善，給工程造價(jià)管理帶來不便。 本文對(duì)強(qiáng)夯法與其它地基處理方法在工程造價(jià)方面的優(yōu)勢(shì)進(jìn)行了分析比較，對(duì)天津市、廣東省和江西省的強(qiáng)夯預(yù)算定額進(jìn)行了分析研究，結(jié)合工程實(shí)際對(duì)江西省強(qiáng)夯法中低能級(jí)預(yù)算定額進(jìn)行了優(yōu)化、中高能級(jí)預(yù)算定額進(jìn)行了測(cè)算和補(bǔ)充。得到如下主要結(jié)論和成果： 1、我國(guó)現(xiàn)行的強(qiáng)夯地基處理預(yù)算定額在地域上相互封閉，，在時(shí)間上較為滯后。天津市強(qiáng)夯法預(yù)算定額僅僅列出了2000kN.m以下能級(jí)對(duì)應(yīng)的子目，廣東省、江西省也僅僅列出了4000kN.m以下能級(jí)對(duì)應(yīng)的子目。沒有目前廣泛適用的6000kN.m能級(jí)所對(duì)應(yīng)的子目，更沒有18000kN.m高能級(jí)強(qiáng)夯所對(duì)應(yīng)的子目。 2、天津、廣東和江西的強(qiáng)夯地基處理預(yù)算定額相比，廣東的預(yù)算定額子目清晰，水平較高，可作為其他省市強(qiáng)夯法地基處理定額優(yōu)化的參照。 3、對(duì)江西省1000kN.m、2000kN.m、3000kN.m、4000kN.m能級(jí)的強(qiáng)夯預(yù)算定額做了參考性的優(yōu)化，比現(xiàn)有的定額消耗量小，定額水平有所提高。 4、對(duì)江西省5000kN.m、6000kN.m能級(jí)的強(qiáng)夯預(yù)算定額做了測(cè)算和參考性的補(bǔ)充。 論文研究成果對(duì)完善強(qiáng)夯地基處理方法，豐富強(qiáng)夯地基處理法的造價(jià)管理理論有一定的理論和實(shí)踐意義。
[Abstract]:The treatment method of dynamic compaction foundation is widely used at home and abroad because of its simple construction technology and low engineering cost, but its budget quota is not perfect, which brings inconvenience to the project cost management. In this paper, the advantages of dynamic compaction method and other foundation treatment methods in engineering cost are analyzed and compared, and the budget quota of dynamic compaction in Tianjin, Guangdong Province and Jiangxi Province is analyzed and studied. Based on the engineering practice, the low and low level budget quota of dynamic compaction method in Jiangxi Province is optimized, and the medium and high level budget quota is calculated and supplemented. The main conclusions and results are as follows: 1. The current budget quota for dynamic compaction foundation treatment in China is closed to each other geographically and lags behind in time. The budget quota of the dynamic compaction method in Tianjin only lists the sub-items corresponding to the energy levels below 2000kN.m, and the corresponding subitems of the energy levels below the 4000kN.m level in Guangdong and Jiangxi provinces are listed only. There is no subhead corresponding to the 6000kN.m energy level, which is widely applicable at present, and no subhead corresponding to the 18000kN.m high-energy dynamic compaction. 2. Compared with the budget quota for dynamic consolidation foundation treatment in Tianjin, Guangdong and Jiangxi, the budget quota subitems in Guangdong are clear. The level of dynamic compaction is relatively high, which can be used as a reference for optimizing the norm of foundation treatment by dynamic compaction method in other provinces and cities. 3. The reference optimization is made for the dynamic compaction budget quota of 1000kN 路m ~ (-1) 2000kN 路m ~ (-1) energy level in Jiangxi Province, which is less than the current norm consumption. The quota level has been improved. 4. The calculation and reference of the dynamic tamping budget quota of the energy level of 5 000 kN.mr. m in Jiangxi Province have been made. The research results of this paper have certain theoretical and practical significance for perfecting the treatment method of dynamic compaction foundation and enriching the cost management theory of dynamic compaction foundation treatment method.
