英文摘要：

Flat geotextile sand tube (geotube) embankments are widely used for estuarine and costal structures. The structures are prone to collapses for the reason of complex construction environment. It is of significance to improve the safety and efficiency of construction by introducing information construction technology. In the first step, the factors which have influence on the stability of flat geotube embankments during construction period are screened, then stability calculation methods for the geotube embankments are proposed for each factor. In the second step, an information construction system (software and hardware) is developed based on the proposed formulae. Finally, field application of the system and filed experiment are presented based on a typical project. According to the results of field experiment, it is indicated that the proposed system can satisfy the requirements of normal operation in the process of construction.
