| description | The “Autopista del Café” in the stretch comprehended between the cities of Manizales and Pereira showssome unstable geological sites who has demanded great money expenses for stabilization. One of them iscalled “San Peregrino”, located at abscissa K7+630 of the roadway Manizales-Pereira. The road in this sector pass along a ridge water divide about 20 meters wide on top, an manifests severe geological stability problems toward both sides of ridge.. The water divide is constituted by thick beds of black shales which are interstratified with thin beds of chert of centimetric dimensions, disposed in the form of a fold with its axis oriented along the water divide. The zone is affected by the Fundamental Romeral Fault causing high fracturation grade in cherts beds, gravity folds in the shales and complex superimposed folds in all the sequence, characteristhics that together with high flow of underground water, have caused stability problems in the area with the consequent demand of a high inversion in stabilization works. The implemented stabilization works until now, are superficial and subterranean drainage, and several aligned caissons to protect the highway floor. |

La “Autopista del Café” en el tramo comprendido entre las ciudades de Manizales y Pereira presenta varios sitios de inestabilidad geológica que han demandado grandes cantidades de dinero para lograr su estabilización. Uno de estos sitios se denomina San Peregrino, y se localiza en el km 7+630 de la vía Manizales – Pereira. En este sitio la autopista está a lo largo de una divisoria de aguas de 20 m de ancho, donde se presentan problemas de inestabilidad geológica severos en ambos lados de la divisoria. La divisoria está constituida por gruesos paquetes de shales carbonosos interestratificados con delgadas capas de chert de dimensiones centimétricas, dispuestas formando un pliegue con eje a lo largo de la divisoria. La zona está afectada por el trazo dela Falla Fundamentalde Romeral, lo que ha producido alto grado de fracturación en los cherts, plegamientos de gravedad en los shales y pliegues complejos superpuestos en toda la secuencia, características que junto con el alto flujo de agua subterránea, han desestabilizado el sitio hasta el punto de requerir una gran inversión en obras de estabilización. Las obras de estabilización implementadas hasta ahora, son drenaje superficial y subterráneo, y una batería de caissons para proteger la banca de la vía.
