First, based on site survey, preliminary engineering geological evaluation on the wall rock was made and it was concluded that the wall rock was in unstable status. 首先,根据现场调查,对围岩进行了初步的工程地质评价,认为该岩体处于不稳定状态;
This integrated approach provides for the streamlining of the preliminary engineering process and allows the design to progress without undue delay. 上述综合方法使初步工程流程流线型化,并使设计进展无不当延误。
Then, after summing up the law of numerous data of shock environment, the forecasting formula has been obtained using regression analysis. Its prediction effect has been verified in order to be applied to forecast the shock environment in preliminary engineering. 然后,在总结大量冲击环境数据变化规律的基础上,采用回归分析方法得到了冲击环境的预报公式,并对其预报效果进行了验证,旨在将其应用于冲击环境初步工程预报。
Effect of the State Investment System Reform on the Preliminary Engineering(PE) in Petroleum Construction Project 国家投资体制改革对石油建设项目前期工作的影响
The preliminary engineering risk recognition and measurement system is developed based on the fault tree model and IT technology, by using the recognition unit of part engineering and part item of the whole engineering. 初步构建了以分部分项工程为识别单位,以故障树为主要分析模型,依托信息技术的工程风险识别和度量系统。
