摘要:
文章以高速铁路路基分段堆载为研究依据，由太沙基一般固结理论和渗透系数与孔隙比的经验关系，推导了分级连续加载下地基沉降的固结控制方程，根据方程的解析解，建立了分级连续加载下饱和中-低压缩性土地基沉降的计算公式。结合海南东环客运专线、云桂高速铁路建设，基于建立的分级连续加载地基沉降计算公式，计算了高速铁路路基分段堆载下，花岗岩全风化土地基、黏土地基的沉降发展趋势，并通过理论计算与实测结果的对比，验证了计算方法的合理性。
Abstract:
Taking the stage loading of subgrade for high-speed railway as the object of study, based on Terzaghi consolidation theory, the relationship between permeability coefficient and void ratio, the equations for consolidation of foundation settlement under stage continuous loading is derived. According to analytical solutions of the above equations, a formula for settlement calculation of saturated medium-low compression soil foundation under stage continuous loading is established. Combined with the construction of east ring dedicated passenger railway in Hainan and Yun-Gui high-speed railway, settlement trend of completely decomposed granite foundation and clay soil foundation are calculated with that formula. The theoretical values of settlement are compared with test results,then the rationality of the calculation formula is verified.
