| 摘 要： | 针对锡澄高速公路与沪宁高速公路拼接段采用的定喷隔离墙加固施工措施，应用土体固结非线性有限元法，就隔离墙在工程中所起的作用进行数值模拟。计算分析表明，隔离墙的存在可有效地减少锡澄高速公路拼接后对沪宁高速公路主线中心的附加沉降量。同时对隔离墙进行验算，给出了隔离墙两侧的受力分布及位移规律，计算结果满足墙体的设计强度。

| Abstract: | In this paper,the non linear finite element method(FEM)for Biot consolidation of soil is applied to the analysis of the separation wall used to reinforce the road bed fundation of the conjunct section of Wuxi-Jiangyin expressway and Shanghai Nanjing expressway.The result of analysis indicates that additional settlement in the original Shanghai Nanjing expressway after connected with Wuxi-Jiangyin Expressway will be reduced and the strength of the separation wall satisfies the designed requirement. |
