Based on the analysis of the stress distribution law in different districts around the self - closed and full - connected arch walling support roadway, the relationship among the limit equilibrium radius and the in - situ rock stress, the physico - mechanical properties and support parameters is obtained. the calculation formula of arch walling width design is put forward so as to provide a theoretical basis for the practical design of support
在分析自封閉全接觸碹體支護巷硐周圍不同區域應力分佈規律的基礎上，得出了圍巖極限平衡區半徑同巷硐所處的原巖應力，圍巖本身的物理力學性質及碹體支護參數間的相互關系，提出了設計碹體厚度的計算公式，為實際進行支護設計提供了理論依據。 -
Abstract : a new data structure that one link - list was composed of polygon - surface table, edge table and vertex table was proposed to describe the geometry information and topology information of control polyhedron m in the rese arch of modeling with closed surface. compared with other structures which were a pplicable to the work, the structure was understandable, economize and conveniently to modify. after describing the detail of the geometry information, topology inf ormation included in the tables of polygon - surface, edge and vertex, and the poin t - link form of the adjacency multilist between the tables, a concise instance was given in clanguage array
文摘:介紹了在閉曲面造型研究中，為描述控制多面體m的幾何信息和拓撲信息而設計使用的一種單鏈三表的數據結構.與其他適用與描述控制多面體的數據結構相比，該結構在結合了鄰接多重表方法后的特點是:關系描述清楚，節省存儲空間，方便查找和交互修改形體.在介紹單鏈中三表（面表、邊表、頂點表）所含的幾何信息細節、以及單鏈的三表之間的表示面、邊、頂點拓撲關系的指針的鄰接多重連接方式之後，本文給出了以c語言數組方式簡明描述的數據結構實例 -
