摘　　要：为解决国外港口工程测量中UTM投影变形问题,比较了UTM投影与高斯-克吕格投影的异同点,推演了UTM投影的长度变形的计算公式,探讨了一种建立独立坐标系的方法,并用工程实例证明此方法的可行性。To solve the problem of UTM projection distortion in overseas port engineering surveying,compared UTM projection with Gauss-Kruger projection,deduced the formula of UTM projection length distortion,discussed a solution to establish an independent coordinate system,and proved the feasibility of this solution by engineering example.
