You tourists, the area where we are now are the area of the cave. By the roadside is Barn swallow hole. This hole goes through the Yangtze River and was named swallow hole Because of too much Swallow inside. Lack of repairs in long-term, it has been dust-laden for a long time and occupied by the bats. People can hardly enter it.
各位游客，我们现在所在的景区就是溶洞分布景区了，路边这个洞口便是燕子洞洞口，此洞直通长江，因洞内燕子较多，故成为燕子洞，现因长久未修，洞内已尘封多时，为蝙蝠占据栖息，人难以入内。

The selection of geological prospecting in different stages(initial-prospecting, detailed-prospecting)(2)the selection of geological prospecting in the deep-laid and shallow-laid of tunnel project (3)the selection of geological prospecting of tunnel projecting in different geological conditions Finally, the author summed up main problems needing to be solved in tunnel engineering geological prospecting as follow:(1)differentiate stratum and find out the depth and thickness of different stratums in the tunnel section (2)find out geological structure and existence situation of fault, broken zone and weak plane (3)find out weathering level of bed rock to classify surrounding rock combining speed materials (4)differentiate stratum structure of the entrance of tunnel to judge the stability of it (5)find out existence situation and performance of ground water (6)situations of other harmful geological phenomenon In view of above problems and classification of surrounding rock, the author showed principles of rational choosing of methods in geological prospecting and counted disperse range of physical character parameter value in different petrosal character, getting achievements as follow:(1)summarization of effect, merits and demerits of different geological prospecting methods in the tunnel geological investigation (2)method selection and arrangement principle of tunnel engineering geological prospecting in different geological conditions and prospecting stages (3)According to previous experience and cases, the author concluded the物性parameters most in use ,and showed the basis of selecting geological prospecting methods in different geological conditions.
论文中用几个应用实例来说明：(1)不同勘察阶段物探工作的选用；(2)深埋、浅埋隧道工程物探工作的选用；(3)不同地质条件隧道工程物探工作的选用。最后总结归纳出隧道工程物探所需要解决的问题主要有：(1)划分地层，查明隧道通过剖面的各地层深度与厚度。(2)查明地质构造，隧道轴线段有无断层、破碎带、软弱层面等。(3)查明基岩风化程度，从而结合速度资料进行围岩分级。(4)划分洞口地层结构，判断洞口稳定性。(5)查明地下水赋存情况及其活动动态。(6)其他不良地质现象存在情况。针对上述需要查明的地质问题与计算围岩分级情况，论文提出合理选用物探方法的原则，并统计了物性参数值在不同岩性中的分布范围。得出以下研究成果：(1)总结出各物探方法在隧道地质调查中的作用和优缺点。(2)得出不同地质条件下和不同勘察阶段，隧道工程物探方法选择和布置的原则。(3)根据以往工作经验和事例，对常用的物性参数进行了归纳总结，同时介绍了不同地质条件下物探方法选择的依据。

There is a kind of monkey trap used in Asia, a coconut is hollowed out and attached by a rope to a tree or stake in the ground, at the bottom of the coconut a small slit is made and some sweet food is placed inside, the hole on the bottom of the coconut is just big enough for the monkey to slide in his open hand, but does not allow for a closed fist to pass out, the monkey smells the sweets, reaches in with hand to grasp the food and is then unable to withdraw it, the clenched fist won't pass, through the opening, when the hunters come, the monkey becomes frantic but cannot get away, there is no one keeping that monkey captive, except the force of its own attachment, all that it has to do is to open the hand, but so strong is the force of geed in the mind that is a rare monkey which can let go, it is the desires and clinging in our minds which keep us trapped, all we need to do is to open our hand, let go of our selves, our attachment and be free.
在亚洲某些偏远地区﹐流传著某种传统捉猴子的陷阱﹐他们把椰子挖空﹐然后用绳子绑起在树上或固定在地上﹐椰子上留了一个小洞﹐洞内放了一些美饵﹐洞口大小恰好只能让猴子空著手伸进去而无法握著拳伸出来﹐於是顽猴闻香而来﹐将手伸进去抓拿美食﹐而后理所当然的﹐手便伸不出来﹐紧握的拳头伸不出洞口﹐当猎人到来时﹐羣猴惊慌失措﹐但﹐就是逃不掉﹐并没任何人捉著猴子不放﹐它﹐只是被本身的执著所俘虏﹐它只需将紧握的手拳头松软放开便可伸出来﹐但是﹐就是内心中贪恋的欲念所致﹐鲜有顽猴能放下﹐因内心中的欲望与执著﹐使得我们一直受縳﹐面对这逆境﹐我们唯一要做的﹐只是将双手释然放下﹐放下自我执著的坚持﹐就能消遥自在了。
