Bajadock: Green route above is approximation of the alternative route that has been discussed to bypass the fault zone. Lots of talk(chisme), but, there is no budget, no plan and no action.
elvigia.net The heavy concentration of water in the subsurface geological faults and the slope of the land, are the main risks to the Tijuana-Ensenada Scenic Road.
Such circumstances over the decades generated a series of damages to the highway, reason why employers insist on an alternate route criteria.
And if the project is promoted to consolidate federal authorities, geological studies should be made, as in the area posed to an alternate road there from rock to unstable ocean floors, changing topography and ancient landslides warned Luis Mendoza Garcilazo.
The researcher in the area of Seismology Division of Earth Sciences of the Center for Scientific Research and Higher Education of Ensenada (Cicese), pointed out that the definition of the new line should be accompanied by studies of geology of soil instability.
“We do not expect to make a line to connect two points of the free road to Tecate line the road,” he said.
That said, given the likelihood that the road crossing unstable faults or old landslides.
“We do not know the exact outline of what is proposed as an alternative route, but they will cross different types of geological materials, from rock to unstable ocean floors, changing topography …” he reiterated.
From the result of studies -precisó-, you can determine whether it is necessary to provide water collectors, works, water conveyance, among other things.
The risks for rain
Regarding the risks that may represent the next rains fault zone for the Scenic Road -a height Salsipuedes- Bay, the researcher specified that “it is not necessary to have torrential rains, as the light and allows constant rain more infiltration of water to the land “
After the cracks detected at kilometer 95, Mendoza explained that Garcilaso each of the nine sites identified as unstable “have a different dynamic, a different geology and faults and fractures in different directions, and a different type of material.”
Based on the conditions of each point (as determined by studies), it is how you should plan preventive works, “whether they infiltration galleries, retaining wall, or what engineering determine. We assume that is what they are doing in charge of the highway”.
Luis Mendoza reported that for 13 years began to collaborate with the Secretariat of Communications and Transportation (SCT) and Federal Roads and Bridges (Capufe) in Salsipuedes Bay, where they have detected nine points with unstable road surface evidence.
Since it was proposed to monitor these sites it is recommended that monitoring is constant for its speed and direction of movement.
“It is documented in publications and thesis kilometer 98 in previous years the phenomenon occurred, and at kilometer 95, where are appearing new cracks, was an event in 1983 in Saldamando, like at kilometer 90,” he recalled.
