A log bridge is a timber bridge that uses logs that fall naturally or are intentionally felled or placed across streams. The first man-made bridges with significant span were probably intentionally felled trees. The use of emplaced logs is now sometimes used in temporary bridges used for logging roads, where a forest tract is to be harvested and the road then abandoned. Such log bridges have a severely limited lifetime due to soil contact and subsequent rot and wood-eating insect infestation.

  • Un pont de troncs és un pont de fusta que utilitza troncs , ja hagin caigut de manera natural o s'hagin tallat i col·locat intencionalment a través de rierols. Els primers ponts artificials amb un abast significatiu eren probablement arbres talats intencionadament.L'ús de troncs emplaçats sobre rierols, s'utilitza de vegades en ponts temporals emprats en l'explotació de carreteres, on s'ha de fer servir un tracte forestal i abandonar-lo després. Aquests ponts de troncs tenen una vida molt limitada causa del contacte amb el sòl, la putrefacció subseqüent i la infestació d'insectes que es mengen la fusta. (ca)

has abstract
  • Un pont de troncs és un pont de fusta que utilitza troncs , ja hagin caigut de manera natural o s'hagin tallat i col·locat intencionalment a través de rierols. Els primers ponts artificials amb un abast significatiu eren probablement arbres talats intencionadament.L'ús de troncs emplaçats sobre rierols, s'utilitza de vegades en ponts temporals emprats en l'explotació de carreteres, on s'ha de fer servir un tracte forestal i abandonar-lo després. Aquests ponts de troncs tenen una vida molt limitada causa del contacte amb el sòl, la putrefacció subseqüent i la infestació d'insectes que es mengen la fusta. Els ponts de tronc més duradors es poden construir utilitzant troncs tractats i/o proporcionant bases ben drenades de pedra o formigó combinades amb un manteniment regular per tal d'evitar la infiltració del sòl. Aquesta cura en la construcció es pot veure el pont de l'Alzou il·lustrat a la foto, que compta amb pilars de pedra ben tancats i secs i amb un camí anivellat amb taulers. (ca)
  • A log bridge is a timber bridge that uses logs that fall naturally or are intentionally felled or placed across streams. The first man-made bridges with significant span were probably intentionally felled trees. The use of emplaced logs is now sometimes used in temporary bridges used for logging roads, where a forest tract is to be harvested and the road then abandoned. Such log bridges have a severely limited lifetime due to soil contact and subsequent rot and wood-eating insect infestation. Longer lasting log bridges may be constructed by using treated logs and/or by providing well drained footings of stone or concrete combined with regular maintenance to prevent soil infiltration. This care in construction can be seen in the French bridge illustrated below, which has well locked dry set stone abutments and a footpath leveled with boards. (en)
