探洞

高地应力条件下Q系统在某勘探洞围岩分类中的应用

Application of Q - System in Classification of Surrounding Rock in Tunnel under High Ground - Stress

两年前，南非科学家按照洞穴探险爱好者的指引，在启星洞（RisingStarCave）深处发现了探洞者通过石灰岩壁上的缝隙隐约瞥见的东西：大量古老的骨头。

Acting on a tip from spelunkers two years ago , scientists in South Africa discovered what the cavers had only dimly glimpsed through a crack in a limestone wall deep in the Rising Star cave : lots and lots of old bones .

山东文登抽水蓄能电站在探洞开挖至400m处，遇到断层带，并发生涌水问题，造成部分洞段出现塌方。

When the testing tunnel for Wendeng Pumped Storage Power Station in Shandong province is excavated to 400m , a fault zone crosses the tunnel and water inrush occurred , which induced the collapse .

在探洞深部地应力应力值较高，最大主应力为40MPa左右，作用方向近直立；

The in-situ stress at deep depth of tunnel is higher , the maximum stress is about 40 MPa , and the direction is about vertical .

结果：EGb可明显升高Na+-K+ATP酶活性，缩短中央格停留时间、水迷宫实验逃避潜伏期时间，提高探洞次数和搜寻平台策略成绩。

RESULTS EGb could increase Na + - K + ATPase activities of both cerebral cortex and hippocampus in the diabetic rats , and improve the hole-probe trial performance in open field test and shorten the escape latency time in Morris water maze .

探洞人怕被淹死吗？

Were the cavers scared of drowning ?

19岁的卢卡斯·卡瓦尔和印第安纳大学探洞俱乐部于日前前往印第安纳州南部的沙利文洞里参观。

Lukas Cavar , 19 , was visiting the Sullivan Cave in southern Indiana with the Indiana University Caving Club .

当探洞俱乐部的主席意识到卡瓦尔失踪并返回岩洞之后，他才被救出。

He was rescued when the president of the Caving Club realised he was missing and returned to the cave .

韩恩洞的中部洞高缩小，探洞人正在经无数年洪水冲刷磨圆的洞顶下通过。

Headroom shrinks in the middle of Hang En as cavers pass beneath a ceiling scalloped by eons of floodwater rushing past .

洞板实验中模型组小鼠潜伏期延长，探洞次数减少（P<0.01）。

In hole-board test , the latency period prolonged and the times of extending the holes decreased significantly ( P < 0.01 ) .

位山穿黄探洞应急加固工程大堤安全监测仪器安装埋设、观测及分析

Installation , observation , and data analysis of safety monitoring instruments used in the Yellow River dike project for reinforcing treatment of exploratory tunnel through the Yellow River at Weishan

饰出了凹槽的瀑布，看起来象一个石化的瀑布，被藻类染绿，止住了肃然起敬的探洞人的脚步。这里已靠近韩恩洞的出口。

Like a petrified waterfall , a cascade of fluted limestone , greened by algae , stops awestruck cavers in their tracks . They 're near the exit of Hang En .

该探洞俱乐部则称：“我们拥有一系列预防这种类似情况的严格协议，但是只有在遵守的时候才有效。在严格遵守所有安全程序上，我们的领导出现了失误。”

The Caving Club said : " We have a series of rigorous protocols in place that are supposed to prevent situations like this , but they are only effective if followed . We had a failure in our leadership to closely follow all these safety procedures . "
