Abstract


Littoral silt foundation built highways process , the factors that affect the deformation and stability is more complicated . This article relying on city roads soft foundation reinforcement projects , according to the the site engineering characteristics of the proposed comprehensive reinforcement measures and carry out field trials research , while taking advantage of the large number of measured data on tides and rainfall under the influence of littoral silt subgrade deformation characteristics analyzed , the paper obtained the following main conclusions : first the Xiamen Haicang littoral mud engineering characteristics and environmental diversity the packed sand overload preloading combined cofferdam reinforcement measures , and test programs overall design and validation ; summary of the construction process of the coastal Soft Soil reinforcement measures , to refine the construction preparation, construction processes and precautions . The site engineering reinforcement measures for long-term monitoring , to verify the effect of reinforcement measures through the analysis of the measured data and the settlement speculate ; considering Cang littoral mud engineering properties of embankment stability , construction , and other factors , demonstrated by finite element analysis the feasibility of reinforcement measures . Coastal soft soil subgrade deformation analysis of fill height , thickness of the sludge loading rate and tidal rainfall role influencing factors . Test subgrade deformation data to establish the settlement class foundation before unloading and loading rate , calculate the empirical formula , which provides the basis for a reasonable construction schedule control ; according to test data analysis for the basic law of the tides and rainfall under the influence of soft roadbed settlement deformation .
