Abstract: While establishing the project control network , It usually encounters coordinated point and established fundamental point some or all of the same , class , this paper uses fundamentals of generalized smoothen .It can effectively solve the problem of start data smoothen , and pledye the precision of the project control network

Key words: fundamental network , precision , smoothen

摘要： 在布设工程控制网时，常遇到依据点与所布点部分或全部同级的情况，笔者应用广义平差原理，有效地解 决了起始数据平差的问题，从而保证了控制网精度
