堤防一体化复合灌浆软件开发及工程应用

Development and Engineering Application of Integrated Compound Grouting Software for Levee Project

已有城镇堤防改造加固表明,基于“自上而下钻灌一体脉冲灌浆”+“自下而上无返浆高压旋喷灌浆”城镇堤防一体化复合灌浆技术应用越来越广。长久以来,科研单位注重于国外商业软件二次开发,设计公司更注重于生产,基于基础规范开发基础性功能软件甚少。以规范标准为基础,采用c++语言编制程序,开发含堤防几何参数、土体性能参数、复合桩参数、稳定计算参数、渗流计算参数5类参数输入,整体稳定、渗流稳定、承载力计算、沉降计算、工艺参数5类结果输出为主的堤防一体化复合灌浆设计软件,经与其他国外通用商业软件对比分析,计算结果相对吻合。计算程序更适用于设计人员,程序可以用于土石坝、堤防设计计算。

The reconstruction and reinforcement of existing urban levees show that the integrated compound grouting technology based on“Top-down drilling and pulse grouting”+“Bottom-up non backflow high-pressure rotary jet grouting”is more and more widely used.For a long time,because the scientific research institutions are focused on the secondary development of foreign commercial software and the design companies are only focused on production,there is very little basic functional software developed based on basic specifications.An integrated compound grouting design software based on basic specifications is developed with C++language,in which,five kinds of parameters are used as inputs,including embankment geometric parameters,soil performance parameters,composite pile parameters,stability calculation parameters and seepage calculation parameters,and five kinds of result outputs can be obtained,including overall stability,seepage stability,bearing capacity calculation,settlement calculation and process parameters.The developed software is compared with other foreign general commercial software,and the calculation results are relatively consistent.The calculation program is more suitable for designers,and it can be used for the design and calculation of earth-rock dams and levees.
