水泥搅拌桩与夯实水泥土桩在高速公路中的应用

Application of Cement Mixing Pile and Pamped Cement-soil Pile in Expressway

结合河北省保沧高速公路建设工程实践,在分析水泥搅拌桩与夯实水泥土桩的处理机理和适用范围的过程中,着重对其设计方法、施工工艺、质量检测和优缺点等进行分析和研究,结果证明,只有结合软基处理方法的原理、适用范围及条件,才能选择出既节省工程造价又能达到良好使用效果的最优方案。

Combined with the construction project practice of Hebei provincial Baoding-Cangzhou expressway, in the analyzing of the treatment mechanism and scope of application of cement mixing piles and tamped cement-soil piles, their design method, construction technology, quality inspection, advantages and disadvantages are discussed emphatically. It can be summarized that only combined with the principle, the scope and condition of application of soft foundation treatment method can select the optimal scheme which can save construction cost and achieve good application effect.
