摘要
提出了通过数学方法求解钻孔孔位在空间的最短距离及最接近点位置并结合孔偏来判断其在空间是否交叉的方法及准则。采用该方法可以对各种不同用途的钻孔在空间的交叉情况进行准确判断,尤其是对于边坡加固中大量锚索和监测仪器孔或排水/观测洞室等穿插布置的情况,可以避免异常麻烦的孔位交叉判断图上投影作业。该方法也可用于大坝工程灌浆、取芯、物探等或土建工程中钻孔与水管或电缆交叉情况的判断。
This paper presents the method and criterion for judging the spatial intersection of drill holes, by determining the shortest distance between two spatial segments and the nearest point thereon. It can be used to evaluate the spatial relationship between drill holes for different purposes. The complicated projection operations on drawings can be overcome especially in the case of a great number of anchorage cables being interwoven with drill holes for instrumentation and drainage/observation galleries in slope stabilization engineering. It can also be used to judge the spatial intersection of drill holes for grouting, coring and geophysical exploration and pipes or cables in dam engineering and civil engineering.
