高速铁路线路控制网(CPⅡ)在高速铁路建设中起着施工平面控制的作用，其复测工作一般分标段完成，而且可能由不同测量队负责，因而会出现不同测量队完成的控制网测量数据无法严格“接头”现象。施工单位负责标段内高速铁路施工控制网复测超限会引起高速铁路线下施工放样出现偏差，最终可能导致整条线路无法顺利连通。 论文主要从两方面对施工放样偏差进行改正。首先，从施工控制网复测本身入手，分析测量参考椭球归算中产生的误差、平面投影变形误差等对控制网复测精度的影响，并通过一系列的误差改正计算提高复测结果的可靠性；其次，从施工放样入手，分析高速铁路线下工程施工放样中出现偏差的类型，设计恰当的放样改正方案，计算放样改正坐标，直接在施工放样过程中纠正偏差。研究发现，应用改正计算、模拟抵偿等方法可以有效降低测量误差带来的影响，但是改正后坐标使用范围仍然有局限，超出限制范围后变形再次超限。施工放样过程中纠正线路偏差是一种机械式的改正方法，经过改正可以达到预期目的，但需要争取相关负责单位的同意。 高速铁路高程控制网测量主要包括线路水准基点以及轨道控制网(CPⅢ)的高程测量。论文主要针对线路水准基点高程测量以及施工加密高程点的高程测量方法进行研究，探讨用全站仪三角高程测量代替二等水准测量的方法，以及GPS高程测量的应用问题。研究表明，全站仪三角高程测量代替二等水准测量时，需要对全站仪或棱镜进行改装，测量结果虽然在理论上可以达到精度要求，但是要广泛应用到实例还需要更进一步研究。对GPS水准高程测量在高速铁路跨河高程控制点复测中如何使用，推导出了两岸高程点间高差计算公式。

The line control network (control point Ⅱ) plays the role of the construction plane control in high-speed railway construction. The retest work generally finished by different tenders, and may be responsible by different measurement teams. So there will be some measurement dates which can not be strictly connector. The retest overrun of high-speed railway construction control network within the construction unit tenders will cause deviation of High-speed rail line project engineering construction stakeout, and may eventually lead to the entire line can not be smoothly connected. There are two major kids of correction about the construction stakeout deviation in this paper. First of all, start from retest of the construction control network. Analysis the impact of the control retest accuracy, what caused by the measurement reference ellipsoid imputing error and planar projection distortion error and so on. Improve the reliability of the results of the retest through a series of error correction calculation. Secondly, start from the construction stakeout. Analysis types of the deviation that appear from High-speed rail line project engineering construction stakeout, design the appropriate the loft correction program, calculation of the loft to correct coordinates. Correct deviations In the process of construction stakeout directly. Study found that, using correction calculation, simulation satisfaction etc can effectively reduce the affect brought by error. But the using of coordinate are also limited, the error will come back when overrun once again. Correcting deviations In the process of construction stakeout is a mechanical correction. If the responsible units agree with this method, it can make us achieve the desired objective. The vertical control network measurement of high-speed railway major include the height measurement of Line benchmarks and orbit control network (control point Ⅲ). The paper research on some methods which consider in the height measurement of Line benchmarks and encryption elevation points, investigate the methods how to use Trigonometric leveling instead of second leveling by Total Station, and application of GPS height measurement. Studies have shown that the Total Station or prism should be modified in the measurement when we use trigonometric leveling instead of second leveling. In this way, although the accuracy of the measurement results can be achieved in theory requires, to be widely applied to the instance still need further study. In order to explain how to use GPS Height measurement method retest the vertical control points of high-speed railway which crossing river, the author deduced height difference calculation formula of elevation points between both sides.
