摘　　要：胶结充填过程中挡墙的稳定性是重要的安全保障,结合工程实际,通过现场挡墙侧压力监测试验,研究充填过程中挡墙受压情况.试验结果表明,挡墙受充填料浆静水压力、动水压力和固化膨胀力的影响,在充填后期受力最大,最易发生破坏.用公式拟合部分试验数据,结果吻合得很好.通过以上研究计算得到了合理的挡墙厚度.The stability of bulkhead is important to the safety in the process of cemented filling.According to practical situation of the project,the distribution regularity and characteristics of forces on bulkhead in filling were obtained by measuring its lateral stress on the spot.The experiment proved that the stress on the bulkhead was influenced by hydrostatic pressure,hydrodynamic pressure and swelling force of filling slurry.Its stress reaches the greatest in the final filling stage,which is most easily broken.Calculation resulting from formulae fits part of test data satisfactorily.Reasonable thickness of bulkhead has been obtained from the above mentioned study.
