Detección gravimétrica de anomalías del subsuelo en una zona urbana afectada por hundimientos

Abstract

[ES] En este trabajo se describe un estudio microgravimétrico realizado en Alcalá de Ebro (Zaragoza) destinado a localizar las anomalías del subsuelo que pudieran justificar los hundimientos del terreno acaecidos en la zona. A partir de los datos gravimétricos reducidos se procede a un análisis de la coyarianza y a una predicción mínimos cuadrados para filtrar el ruido observacional y obtener un modelo de anomalías gravimétricas. Mediante un ajuste polinomíal robusto se determina una componente regional y su correspondiente residuo, que es identificado como campo de anomalías locales. Para la inversión de estas anomalías locales se recurre a un ajuste de cuerpos esféricos de densidad anómala.

[EN] This paper describes a microgravimetric study carried out in Alcalá de Ebro (Zaragoza) to locate the subsoil anomalies that could justify terrain sinkings which take place in tbis zone. From reduced gravimetrie data, we apply a coyanance analysis and a least squares prediction to filter observational noise and to obtain a model of gravimetnic anomalies. By means a robust polynomial adjustment, a regional component is detennined and its corresponding residue which is identified as local anomalies field. For inversion of those local anomalies an adjustment of spherical bodies with anomalous densitywas done.
