在雅康高速驾车-中国建设难度最大的高速公路之一-4K
雅康高速东起雅安市对岩镇，经过天全县、泸定县，西至康定市炉城镇。雅康高速公路东接成雅高速公路，路线全长约135千米；雅安段89千米，甘孜段46千米，路基宽度24.5米，项目概算总投资230亿元，批复工期五年，公路全线海拔高度差达到1900米。
雅康高速公路贯通运营以后，近4小时可从成都到康定，比原路程至少节约2个小时，同时，该项目桥隧比高达82%，是全省乃至全国桥隧比最高、施工难度最大的高速公路之一。
雅康高速公路建设，面临安全、经济、生态、便捷等一系列重大技术经济问题的挑战。控制性工程二郎山特长隧道长13.4千米，居全国在建高速公路隧道第二；泸定大渡河兴康特大桥主桥跨径达1100米，同类桥型中居全省第一；长达50千米的隧道群穿越高山峡谷，工程施工极其困难。该项目桥隧比高达82%，是全省乃至全国桥隧比最高、施工难度最大的高速公路之一。全线的海拔高差达到1900米。
工程施工极其困难。项目反复与G318线、水电设施交叉干扰，安全风险高；50千米长的隧道群穿越高山峡谷，施工便道布设于悬崖峭壁，特别是泸康段的隧道群，隧道与G318线垂直高差约580米，有的合同段需在峡谷陡坡上修建约8千米的施工便道才能到达隧道支洞作业点，无法再布设便道的情况下,再打通近1000米的隧道支洞才能到达隧道正线施工，施工便道因展线需迂回近24道回头湾，材料运输、隧道弃渣、电力供应极其困难。位于泸定、康定境内的C16-C18合同段的几家大型施工单位，耗时1年半时间才将施工便道和施工支洞打通，到2016年终于展开主线隧道施工。大渡河兴康特大桥跨径1100米、全省第一，面临极高的地震烈度（八度）、复杂的风场条件、极不稳定的高陡边坡等。二郎山特长隧道长13.4千米，最大深埋1700米、地应力高，易出现岩爆和大变形，穿越13条地震断裂带，存在瓦斯、岩溶、涌突水等不良地质，施工质量和安全风险高，斜井单洞长3.3千米，隧道独头掘进长达6.8千米，斜井建设规模、隧道独头掘进居全国之最。

I watched a lot of Videos about China. I love Chinese People, Chinese Food, Chinese Cities and now I‘m falling in love with Chinese rural areas and landscapes. Hopefully one day I can visit China !! Greetings from Germany 🇩🇪!!

We saw this being built during 2017 when we stayed in YAAN for 3 months. Many expeditions and also a walk through a short tunnel. We both loved your video. David and Lily. Li Chen. Reading England.

Mulțumesc pentru răspuns! Te rog frumos sa scrii pe ecran, când editezi vlogul, câți km are un tunel, pe lângă ce orașe treci și ce obiective turistice sunt în drumul tău! Ești urmărit din toată lumea! Te salut din România, orașul București!
Nice ride! 😊
可以康定走434到塔公在248到318新都桥，风景比康定走318到新都桥好很多。
Excellent and beautiful work, thank you for sharing 🥰🌹

Podem falarem o que quiseram...mais os engenheiros da China são surreais....show. Nota 1000 ( 37:02 ) Por ser tão comprido o túnel , o ar não fica prejudicado devido aos gazes dos motores dos carros?

The hammer and sickle of the red flag is the flag of the CPC, not the flag of the Soviet Union.
The path from the Sichuan Basin to the Qinghai Tibet Plateau is to take the shuttle bus from Chengdu to Moxi Ancient Town every morning. It is a small town surrounded by snow capped mountains, with Gongga Mountain at an altitude of 7500 meters. There are magnificent mountain landscapes represented by glaciers and numerous hot spring hotels nearby
