1. 片石氣冷措施 - 片石氣冷路基是在路基墊層之上設置一定厚度和空隙度的片石層,因片石層上下介面間存在溫度梯度,引起片石層內空氣的對流,熱交換作用以對流為主導,利用高原凍土區負積溫量值大於正積溫量值的氣候特點,加快了路基基底地層的散熱,取得降低地溫、保護凍土的效果。

2. 碎石(片石)護坡或護道措施 - 在路基一側或兩側堆填碎石或片石,形成護坡或護道。碎石(片石)護坡空隙內的空氣在一定溫度梯度作用下產生對流,寒季碎石(片石)內空氣對流換熱作用強烈,有利於地層散熱,暖季碎石(片石)內空氣對流作用減弱,對熱量的傳入產生遮罩作用,減少了暖季的傳熱,達到了降低地溫、保護凍土的效果

3. 通風管措施 - 在路基內橫向埋設水準通風管,冬季冷空氣在管內對流,加強了路基填土的散熱,有利於降低基底地溫,提高凍土的穩定性

4. 熱棒措施 - 熱棒是利用管內介質的氣液兩相轉換,依靠冷凝器與蒸發器之間的溫差,透過對流迴圈來實現熱量傳導的系統。青藏鐵路有32公里路基採用了熱棒措施

5. 此外還有遮陽棚、隔熱保溫、基底換填、路基排水、路橋過渡段、橋涵基礎等等。

1. slabstones air cooled measures - slabstone air cooled roadbed is
establishes the certain thickness and the spatial piece above
the roadbed breaker strip , because the piece about lies
between between the surface to have the gradient of temperature,
causes the piece in air convection, the heat change function take convection as the leadership, is bigger than the size using the plateau frozen earth area negative size the climate characteristic, sped up the roadbed basis stratum radiation, obtains reduces the ground temperature, the protection frozen earth effect.
2. crushed stones (slabstone) the slope protection either the measure - piles in a roadbed side or two sides fills in the crushed
stone or the slabstone, forms the slope protection or . The
crushed stone (slabstone) in the slope protection crevice air has the
convection under the certain gradient of temperature function, the
cold season crushed stone (slabstone) in the air convection
recuperation is intense, is advantageous radiates to the stratum,
the crushed stone (slabstone) in the air convection function
weakens, spreads to the quantity of heat has the shade function,
reduced the heat transfer, had achieved reduces the ground
temperature, the protection frozen earth effect

3. ventilation ducts measures - crosswise installed underground the
standard ventilation duct in the roadbed, the winter cold air transfer
in the tube, strengthened the roadbed earth fill radiation, was
advantageous to reduces the basis ground temperature, enhanced the
frozen earth the stability

2008-03-13 15:20:49 補充:
4. hot good measures - hot sticks are use in the tube the
medium gas fluid two to transform, depend upon between the condenser
and the evaporator temperature difference, the penetration transfer
the circle to realize the thermal conduction system.

4.The Qinghai and
Xizang railroad had 32 kilometers roadbeds to use the hot good
measure
5. in addition also has the visor awning, the heat insulation
heat preservation, the basis trades fills in, the subgrade drainage,
the highway bridge , arch of bridge foundation and so on.
