Se analizaron las características de consolidación y deformación y las condiciones de carga de los cimientos del suelo blando bajo la carga de relleno del terraplén, los métodos de tratamiento de los cimientos de rocas blandas, las condiciones del estrato, los cambios de temperatura y los efectos del tiempo. Como área de estudio se definió la sección K9+280-K11+120 a lo largo de la sección Fu-Nehe de la Carretera Nacional 111. Para resolver este problema se propone un método de estudio para las características de consolidación y deformación de rocas blandas y cimientos de suelos blandos en ambientes de humedales hidrológicos. La distribución generalizada de roca blanda y suelo blando en el entorno de humedales hidrológicos es un problema común de ingeniería geotécnica en las zonas costeras de construcción. Keywords: Hydrological wetland soft rock soil foundation consolidation deformation characteristics settlement The research results can provide a reference for the study, calculation, and design of the consolidation and deformation of soft rock foundation in a hydrological wetland. According to the monitoring results of settlement and pore water pressure, bagged sand wells are more suitable for soft rock foundation engineering treatment in a hydrological wetland. The pore water pressure of soft rock foundation dissipates to varying degrees. The negative temperature has a certain influence on the consolidation settlement of soft rock foundation, which is mainly manifested in the difference between the settlement process of the central separation zone and the roadbed soft soil foundation. The results show that although the wetland soft rock and soil layer is not thick, the settlement of soft rock and soil accounts for more than 80% of the total settlement. The consolidation and deformation characteristics and loading conditions of soft soil foundation under embankment filling load, treatment methods of the soft rock foundation, stratum conditions, temperature changes, and time effects are analyzed.
The study area was limited to the K9+280-K11+120 section along the Fu-Nehe section of National Highway 111.
A study method for consolidation and deformation characteristics of soft rock and soft soil foundation in a hydrological wetland environment is proposed to solve this problem. The widespread distribution of soft rock and soft soil in a hydrological wetland environment is a common geotechnical engineering problem encountered in coastal engineering construction.
