摘要
推导了深层搅拌桩止水帷幕水泥掺入比计算公式。简要地对比分析了相邻桩之间不同视搭接宽度的两种方案。提出了仅考虑主动土压力作用情况下止水帷幕厚度计算方法。给出了止水帷幕与支护桩之间的距离及桩间土保护措施的建议。
Calculation formula of cement-mixed proportion of curtains for cutting off water in deep-cement-mixing piles is deduced. Two different plans of apparent connection length between near pile are briefly contrasted and analyzed. Calculation methods of thickness of curtain for cutting off water are proposed when only active earth pressure is considered. Suggestions about distance between curtains for cutting off water and protecting piles and about protective measure of soil between piles are given.
