目的研究RTK相对静态定位技术来提高北斗系统在桥梁变形监测上的测量精度。方法分析北斗导航系统的定位误差来源,对多种消除误差的方法进行对比研究。研究在卫星信号传播过程中的周跳现象,对传统TurboEdit法进行分析,建立一种平均滑动的算法对TurboEdit法进行改进。结果传统方法在测点1X方向上差值的平均值为1.02 cm,在Y方向上差值的平均值为0.98 cm;在测点2X方向上差值的平均值为1.14 cm,在Y方向上差值的平均值为1.13 cm.改进后的方法在测点1X方向上差值的平均值为0.59

目的研究一种新型方钢管混凝土柱与钢梁套管环板节点,以解决T型连接件与柱壁分离的现象以及外环板在外荷载作用下对节点承载力贡献不足的问题。方法采用ABAQUS对节点在低周往复荷载作用下的力学性能进行有限元分析。研究轴压比、梁柱抗弯承载力比值、套板高度、套管厚度等参数对该新型套管环板节点受力性能的影响。结果套管环板节点为半刚性节点,且具备良好的抗震性能和耗能能力,通过材料强度改变梁柱抗弯承载力比值会影响节点的破坏模态和抗震性能。结论建议轴压比控制在0.4~0.6;套管高度取100~200 mm;套管厚度取6~1
In this work,computational fluid dynamics(CFD)is used to study elbow erosion due to a gas-solid two-phase flow.In particular,the direct simulation Monte Carlo(DSMC)method is used to study the impact of inter-particle collision on the erosion behavior.The
In this paper,the superhydrophobic poly(vinylidene fluoride)/fluorinated ethylene propylene/SiO2/CNTs-EDTA(PFSC-EDTA)composite coating was successfully fabricated and applied for anti-scaling performance.The deposition of CaCO3 on the surface of the super
Flue gas flooding is one of the important technologies to improve oil recovery and achieve greenhouse gas storage.In order to study multicomponent flue gas storage capacity and enhanced oil recovery(EOR)performance of flue gas water-alternating gas(flue g
The ultra-low permeability reservoir is regarded as an important energy source for oil and gas resource development and is attracting more and more attention.In this work,the active silica nanofluids were prepared by modified active silica nanopar-ticles
In a fractured porous hydrocarbon reservoir,wave velocities and reflections depend on frequency and incident angle.A proper description of the frequency dependence of amplitude variations with offset(AVO)signatures should allow effects of fracture infills
The fractures and kerogen,which generally exist in the shale,are significant to the CO2 huff-n-puff in the shale reservoir.It is important to study the effects of fractures and kerogen on oil recovery during CO2 huff-n-puff operations in the fracture-matr
Shale gas reservoirs have been successfully developed due to the advancement of the horizontal well drilling and multistage hydraulic fracturing techniques.However,the optimization design of the horizontal well drilling,hydraulic fracturing,and operationa
