He was a member of the French Academy of Sciences from till his death. Leave a Reply Click here to cancel reply.

Journal of Geotechnical Engineering, Vol. Inhe designed a new sausage-shaped dirigible equipped with three air-filled lobes spaced evenly around the tail as stabilizers, and moved the inner air balloonette from the rear to the underside of the nose, separate from the main gas envelope.

Archived from the original on Essai sur une application des regles des maximis et minimis a quelques keriael de statique relatifs a l’architecture. During three years, France manufactured “Caquot dirigibles” for all the allied forces, including English and United States armies. The actual earth pressure force E a is the sum of the part E ag due to the weight of the earth, a part E ap due to extra loads such as traffic, minus a part E ac due to any cohesion present.

That is, the soil is at the point of incipient failure by shearing due to unloading in the lateral direction. Ekrisel first equation is for the active earth pressure condition and the second for the passive earth pressure condition. That is, kdrisel soil is at the point of incipient failure kkerisel shearing, but this time due to loading in the lateral direction.


The lateral earth pressure is important because it affects the consolidation behavior and strength of the soil and because it is considered in the design of geotechnical engineering structures such as retaining wallsbasementstunnelsdeep foundations and braced excavations. The basic equation for computing the passive caquor pressure coefficient may be developed as follows:.

Instead of evaluating the above equations or using commercial software applications for this, books of tables for the most common cases can be used. It is the minimum theoretical lateral pressure that a given soil mass will exert on a retaining that will move or rotate away from the soil until the soil active state is reached not necessarily the actual in-service lateral pressure on walls that do not move when subjected to soil lateral pressures higher than the active pressure.

One year only after high school, at eighteen years old, he was admitted at the Ecole Polytechnique [3] “year” They used a logarithmic spiral to represent the rupture surface instead.

The limiting horizontal pressures at failure in extension or compression are used to determine the K a and K p respectively. Retrieved from ” https: Slope analysis mass wasting landslide Deformation monitoring automated. In the course of his life, Albert Caquot taught mechanical science for a long time in three of the most prominent French engineering schools in Paris: He noticed the poor wind behavior of these sausage shaped captive balloons, which were ineffective except in calm conditions.

Geotextile Geomembrane Geosynthetic clay liner Cellular confinement. Generally instead of K athe horizontal part K ah is tabulated.

Jaky [1] caqhot normally consolidated soils:. Inat 80 years old, Albert Caquot resigned from all the presidencies which he had always assured voluntarily. Terzaghi and Peckindeveloped empirical charts for predicting lateral pressures.

The negative angle of wall friction might develop in the case of positive batter piles subjected to lateral loads, and also in the case of pier foundations for bridges subjected to lateral loads. From Wikipedia, the free encyclopedia. Soil mechanics Foundations buildings and structures. They indicate that for a given value of 0 the value of Kp increases rapidly with increasing values of 8.

Wikimedia Commons has media related to Albert Caquot. This modification is extremely important for passive earth pressure where there is soil-wall friction. For soils with cohesion, Bell developed an analytical solution that uses the square root of the pressure coefficient to predict the cohesion’s contribution to the overall resulting pressure. On-site Cone penetration test Standard penetration test Monitoring well piezometer Borehole Crosshole sonic logging Nuclear densometer test Static load testing Trial pit.

For a level ground deposit with zero lateral strain in the soil, the “at-rest” coefficient of lateral earth pressure, K 0 is obtained.

Inczquot the threat of the war, Albert Caquot was brought back to manage all the national aeronautical businesses. Since the problem is indeterminate[6] a number of potential failure surfaces must be analysed to identify the critical failure surface i.

He always had a great independence of mind and an incredible selflessness. He implemented a policy of research, prototypes and mass production which contributed quickly to France leadership in the aeronautical industry.
