K for a particular soil deposit is a function of the soil properties and the stress history. Warm-hearted, attentive and available, he loved to withdraw within his family. He noticed the poor wind behavior of these sausage shaped captive balloons, which were ineffective kerisell in calm conditions.

InAlbert Caquot became the first executive director of the new Aviation ministry. April Learn how and when to remove this template message. E ag is the integral of the pressure over the height of the wall, which equates to K a times the specific gravity of the earth, times one half the wall height squared.

Archived from the original on Consider a point on pressure surface AB at a depth z from point B Fig For the active pressure acquot, the logarithmic spiral rupture surface provides a negligible difference compared to Muller-Breslau.

Inat 80 years old, Albert Caquot resigned from all the presidencies which he had always assured voluntarily. Two prestigious achievements made him famous internationally: Leave a Reply Click here to cancel reply.

The passive state occurs when a soil mass is externally forced laterally and inward towards the soil mass to the point of mobilizing its available full shear resistance in caqhot to resist further lateral deformation. From tohe was a project manager in Troyes Aubeand was pointed out for major civil work improvements he undertook with the city sewer system. Generally instead of K athe horizontal part K ah is tabulated. From Wikipedia, the free encyclopedia.


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.

The lateral caqkot 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.

Lateral earth pressure – Wikipedia

Atterberg limits California bearing ratio Direct shear test Hydrometer Proctor compaction test R-value Sieve analysis Triaxial shear test Hydraulic conductivity tests Water content tests. At rest lateral earth pressure, represented as K 0is the in situ lateral pressure. Lateral earth pressure is the pressure that soil exerts in the horizontal caquott. Passive earth pressurePassive Earth Pressure Coefficient.

He was visionary and ahead of his time. In the course of his career, as both a highly creative designer and a tireless calculator, he designed more than bridges and facilities among which several were world records at the time:. In this light, the good predictions provided by his solution are often viewed as a coincidence. To estimate K 0 due to compaction pressures, refer Ingold [3]. His major contributions include:.

Please help improve it or discuss these issues on the talk page. The maximum stable value of Merisel is called the passive earth pressure coefficient, K p ; the passive earth pressure would develop, for example against a vertical plow that is pushing soil horizontally.

Albert Caquot – Wikipedia

As early asalready visionary, he performed his military service in an airship unit of the French army. He implemented a policy of research, prototypes and mass production which contributed quickly to France leadership in the aeronautical industry.


The active state occurs when a retained soil mass is allowed to relax or deform laterally and outward away from the soil mass to the point of mobilizing its available full shear resistance or engaging its shear strength in trying to resist lateral deformation.

This applies if the terrace is horizontal or the wall vertical.

Line AC represents an arbitrary plane section through this lower edge. In other projects Wikimedia Commons.

As these are rather expensive tests, empirical relations have been created in order to predict at rest pressure with less involved soil testingand relate to the angle of shearing resistance. Essai sur une application des regles des maximis et minimis a quelques problemes de statique relatifs a l’architecture. November Learn how and when to remove this template message. He was a member of the French Academy of Sciences from till his death. The effective stress is the intergranular stress calculated by subtracting the pore pressure from the total stress as described in soil mechanics.

InAlbert Caquot — and Jean Kerisel — developed an advanced theory that modified Muller-Breslau’s equations to account for a non-planar rupture surface.

In his late eighties, he developed a gigantic tidal power project to capture the tide energy in Mont St Michel bay, in Normandy. Slope analysis mass wasting landslide Deformation monitoring automated. Wikimedia Commons has media related to Albert Caquot.
