非圆形硐室封闭整体式支护映射函数确定的新方法

A NeW MethOd of Determintion Of the Mapping Function for a Non-circle Tunnel with FuII Support

本文利用混合罚函数优化方法，给出了将非圆形硐室封闭整体式支护保角映射成圆环域的方法，该方法基于双连通域的保角变换，克服了以往按单连通域方法计算双连通域问题的缺陷，映射精度远远高于以往的方法。

This paper has presented a method to map full support of a non-circle tunnel onto a annular domain.The mapping function can be obtained by means of the optimiization techniques of mixed penalty function.Themethod is based on the conformal transformation of doubly connected odmain,this overcomes the shortcomings incalculating mapping function of doubly connected domain by means of single domain method. The precision of map-ping function obtained is higher than that of the latter.
