Abrégé

The structural diagnosis method comprises four steps, namely an application step, wherein a mechanical stress is applied by impact to a concrete railroad tie (2, 3) to be diagnosed, a detection step, wherein a vibration generated by the mechanical stress and propagating in the diagnosed tie is detected on the surface of the diagnosed tie and transformed into a time-dependent vibratory signal, a processing step, wherein the time-dependent vibratory signal is electronically processed to obtain a frequency spectrum therefrom, and an analysis step, wherein the diagnosis reference is compared to a structural damage.

Abrégé

Ce dispositif de mesure (200), qui est pratique et performant, comporte un boîtier (210), à solidariser à un pénétromètre dynamique (100), une batterie d'alimentation électrique (250), logée dans le boîtier, et un système électronique (240) qui est logé dans le boîtier et relié à la batterie. Le système électronique comprend un accéléromètre, ainsi qu'un capteur de distance, qui, en service, est orienté vers un sol et qui est adapté pour déterminer la distance entre le dispositif de mesure et la surface du sol en mesurant le temps nécessaire à une onde pour effectuer un trajet aller-retour entre le capteur de distance et la surface du sol. Le système électronique comprend également une unité de traitement qui, lorsque la batterie alimente tout le système électronique, est adaptée pour appliquer un traitement à des signaux de mesure provenant de l'accéléromètre et du capteur de distance.

A measuring device for geomechanical characterization of a soil, the measuring device including a housing, a dynamic penetrometer, a power supply battery, accommodated in the housing, and an electronic system accommodated in the housing and connected to the battery. The electronic system comprises an accelerometer, as well as a distance sensor, which, in use, is oriented towards a soil and which is adapted to determine the distance between the measuring device and the soil surface by measuring the time required for a wave to travel back and forth between the distance sensor and the soil surface. The electronic system also comprises a processing unit which, when the battery powers the entire electronic system, is adapted to apply processing to measuring signals coming from the accelerometer and the distance sensor.

Abrégé

The invention relates to an alveolar geosynthetic blanket for building a structure in reinforced soil, said blanket defining a longitudinal direction (X2) and a transverse direction (Y2) and comprising transverse strips which are connected, particularly sewn, two-by-two, in such a way as to form cells to be filled with filling, the width of the strips corresponding to the thickness of the blanket, and each strip comprising at least one end section (28) which is attached to a corresponding end section (28) of an adjacent strip. The at least one end section (28) of each strip is arranged in the extension of an edge section (30) which extends in the longitudinal direction (X2) when the blanket is deployed and not filled, such that the respective edge sections (30) of the strips are aligned and together form a flat surface of the deployed and non-filled blanket.

Abrégé

This method makes it possible to characterize the seat of a railroad track through penetrometric and geo-endoscopic tests. It includes steps consisting of striking ram head of a light dynamic penetrometer to drive the tip of a train of rods into the seat, measuring the strength of the seat as a function of the pushing in depth of the train of rods, removing the train of rods from the seat, pushing a tube into a hole left by the train of rods, and sliding an image-recording camera inside the tube. The method includes additional automated steps consisting of measuring the position of the camera while it slides inside the tube, i.e., the dep that which the images are recorded, and couplingan analysis of the recorded images as a function of the depth with the strength measurements of the seat to characterize the different layers of the seat.
