针对承压水下条形基坑突涌问题,规范中的突涌稳定计算公式只考虑了坑底隔水土重的影响,而忽略了土层的抗剪强度,文中以水泥搅拌桩加固坑底形成的水泥土为分析对象,通过理论分析和简化假设,采用单向板理论,建立了各种情况下的水泥土临界加固厚度的计算公式,并经过实例成功应用。
Aiming at the inrush of under-pressured strip foundation pit, the calculation formula of outburst stability in the specification only considers the influence of undergroud water-proof soil weight and neglects the shear strength of soil layer. In this paper, The formed cement soil is the object of analysis. Through the theoretical analysis and simplification hypothesis, the formula of the critical thickness of cement-soil under various conditions is established by the one-way plate theory, and the successful application is made through examples.
