含灵敏度约束的变形监测网二类优化设计

2nd-order Optimal Design of Deformation Monitoring Network with Sensitivity Constraint

本文介绍了以灵敏度为主要质量准则的变形监测网二类优化设计的方法。以监测网的总观测权最少为目标函数,以单点灵敏度要求为约束条件,并顾及权的上、下界约束,构成线性规划的数学模型,用单纯形法求解。通过对一个大坝变形监测网观测方案设计说明该法的简便性和实用性。

This paper presents a method for 2nd order optimal design of deformation monitoring network,taking sensitivity as the principal quality criterion.The minimum of general Weight for observation is used as objective function, the sensitivity requirement of points, the upper limit and lower one of weight as Lhe constraint equations to compose mathematical model of linear programming, to which the soluLion is b ased on the simplex method.The method of optimal design is simple and illustrated by the observation seheme design for a dam.
