resumen

El hundimiento del suelo es un problema geotécnico importante que no debe pasarse por alto en el proceso de desarrollo urbano, y es especialmente necesario monitorear y estudiar continuamente el hundimiento del suelo en las ciudades. La aplicación de la tecnología InSAR (Radar de Apertura Sintética Interferométrico) en la monitorización del hundimiento del suelo urbano ha experimentado un desarrollo significativo, desde la adquisición de datos, los métodos de procesamiento, la verificación de la precisión hasta las aplicaciones prácticas. Este artículo se basa en más de veinte años de experiencias del equipo de autores en la monitorización InSAR temporal en Shanghái, acumulando conocimientos desde la exploración aplicada hasta la práctica de ingeniería. Resume sistemáticamente la evolución del monitoreo del hundimiento del suelo urbano, incluyendo la fase experimental inicial, la exploración de métodos basados en pequeños conjuntos de datos, el monitoreo de infraestructuras con el apoyo de datos de alta resolución, y la expansión hacia la monitorización InSAR multiescala y multisource. Con base en los estudios en la región de Shanghái, el equipo de autores también ha llevado a cabo investigaciones de monitoreo del hundimiento del suelo en la llanura de Beijing. Actualmente, el control de la prevención del hundimiento del suelo en Shanghái está en un estado microcontrolado, con la cantidad de hundimiento anual controlada por debajo de 6 mm, lo que impone requisitos muy altos para la monitorización de hundimientos mínimos. De cara al futuro, la monitorización precisa de la deformación de edificios altos densos en áreas urbanas, la comprensión y modelado de los mecanismos de dispersión del radar en escenas urbanas complejas, la explicación científica de los mecanismos de deformación urbana bajo la acción acoplada de múltiples factores, así como la minería de información y alerta temprana apoyadas por inteligencia artificial, impulsarán aún más el desarrollo y la aplicación de la tecnología InSAR.
