He means land below the tunnel and not above. ANy structure needs stable strong support on which it is supported. As everybody knows in last few years, land at Jumja spot has been eroding / giving way considerably and every year the road goes inwards (towards mountain), so the question is if the land below (half pr full) tunnel does get washed away, how will this structure remain in place? I had heard that many high profile engineers from Tala project have spent sleepless nights scratching over this engineering solution. SO, its not as easy as it seems. Had it been (easy), it would have been taken care of long back. However, on the positive side, more complex situations in the world have been tackled successfully so this will also be solved in near future.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-288366913526978753.post-51958352832801089822010-08-04T18:58:12.234+06:002010-08-04T18:58:12.234+06:00well about the word " shame"..its all ab...well about the word " shame"..its all about engineering quality of ours.i am an architecture student myself...hope in future,,,,we be able to come out with solutions....<br /><br />and yeah, thank you sir for changing ur background colour..Sogyelhttps://www.blogger.com/profile/09483617620587924337noreply@blogger.comtag:blogger.com,1999:blog-288366913526978753.post-68856399273198441902010-08-04T09:07:50.548+06:002010-08-04T09:07:50.548+06:00I think your argument is right for full tunnels bu...I think your argument is right for full tunnels but half tunnels can be repaired just like an open highway. Loose soils would require deeper rock bolting and thicker cement grouting. That's why it is costly. But if one considers thousands of man-hours lost every year on the north-south highways, the cost of building the half tunnels would be fraction of such costs.<br /><br />I hear the chief designer for the southern lateral highway is considering the half-tunnel option for landslide areas. Especially between Tala and Kalikhola.<br /><br />Half tunnels have been employed well in the Italian Alps where avalanche occurs every winter. But as you say the Alps are more stable than the Himalayas.<br /><br />The basic question is - isn't a shame that even after 50 years we can't stabilise Bhutan's first highway?Dorji Wangchuknoreply@blogger.comtag:blogger.com,1999:blog-288366913526978753.post-60447088403498388722010-08-03T21:50:23.555+06:002010-08-03T21:50:23.555+06:00nice idea, though. but this very thing about tunne...nice idea, though. but this very thing about tunnel that too in bhutan where soil quality is not that really good, i dont think it will work. Since underground facilities such as tunnels follow closely the motion of their<br />surrounding soils, landslides and seismic faults can be major causes of the damage<br />of these underground structures. In other words, these structures can perform well<br />as long as they are embedded in stable soils. even a slightest crack can cause major damages....in long term these things will become a nuisance...Sogyelhttps://www.blogger.com/profile/09483617620587924337noreply@blogger.comtag:blogger.com,1999:blog-288366913526978753.post-52472648133805975392010-06-24T18:01:43.131+06:002010-06-24T18:01:43.131+06:00The problem in the country is not that people don&...The problem in the country is not that people don't know what to do, people don't do what needs to be done. People know the problems as well as the solutions. Everyone waits for the "zhung" to do everything.<br /><br />Domestic airline? Although I am from the East, I am not in favour of domestic airlines. I would prefer a double-lane running one from Haa to Tashigang and another one running from Samtse to Daifam. These would make more sense. <br /><br />But I do feel domestic helicopter service makes sense because the choppers could also be used for disaster management, evacuation of medical emergencies and deployment rapid reaction forces.Dorji Wangchukhttps://www.blogger.com/profile/09413785867681123146noreply@blogger.comtag:blogger.com,1999:blog-288366913526978753.post-7540435714666878482010-06-14T21:42:47.407+06:002010-06-14T21:42:47.407+06:00Mr. Dorji Wangchuk!
The above HALF TUNNEL is reall...Mr. Dorji Wangchuk!<br />The above HALF TUNNEL is really nice idea! i too feel we must also trade in here in our country. It not only solves the problems from landslides but also looks beautiful. <br />if we think of 100 years from now, it will be the best solution to have stable and beautiful road.<br />But, i think it will be impossible here in our country. see, we can't maintain and care our present nasty road even.<br />Better we have the full tunnel too. It can be made in many places in our coutry.<br />Whatever, i think the concern authority will forget these half tunnel and full tunnel for Domestic airlines are coming up! At last i feel now we are breeding the HAVES and HAVES NOT.<br />tashi delekAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-288366913526978753.post-50198678363104960292010-06-08T20:35:12.758+06:002010-06-08T20:35:12.758+06:00When the land slide occurs, width of several half-...When the land slide occurs, width of several half-tunnels are wipe out.
