1）测量概述

1) Measurement Overview

为满足工程施工特点，该工程的测量控制网按照“从整体到局部，高精度控制低精度”的原则，由高到低设置三级控制网，各级控制网相互衔接，统一为整体系统。

In order to meet the characteristics of construction, the survey control networks of the project have three levels from high to low in accordance with the principle “From the whole to the part; High precision controls low precision”. Control networks at all levels should be connected, thus forming the overall system. 1、测量注意事项

1. Measurement Considerations

建筑物占地面积超大，这对轴线控制网的布设和投测带来难度，需要充分利用高精度电子全站仪进行轴线控制网的布设及细部测量放线，钢尺作为辅助；轴线投测时，仪器要架设在建筑物两端，以减少投测误差。

As the buildings occupy a large area, which brings difficulty to the layout design and measurement of the axis control network, the electronic total station with high precision should be used to lay the network and do detailed survey with steel rulers as assistive devices. When transfer of building lines is conducted, instruments should be erected on both ends of the buildings to minimize measuring errors.

2、测量前准备工作

2. Preparations before measurement

（1）、测量仪器检定：本工程使用的所用测量仪器及工具（包括专业分包的测量仪器）均应经国家计量单位检校合格并在有效时间之内。

(1) Measuring instrument calibration: All measuring instruments and tools (including those used in professional subcontracts) should be examined and calibrated by the national units of measurement and meet the standards within the effective time.
