根据我们在砂土、轻亚粘土、黄土等各种地基土采用强夯法进行加固的实践经验和测试结果,并综合国内外有关实测资料及数据,提出了对梅那尔公式的一些看法,对有效影响深度的计算公式提出了深度影响系数,并提出经验计算公式。文中对各种地基土在强夯作用下孔隙水压力的增长和消散规律,以及振动对附近建筑物的影响,提出了一些看法。另外,还对强夯法的原理进行了初步探讨,提出了爆炸对比法在强夯中的应用。
Based on the practical experience and test results of the reinforced concrete method in sand soil, light sub-clay and loess and other ground soils, and combining domestic and foreign relevant measured data and data, some opinions on the Menar’s formula were proposed. Depth-influence coefficients are proposed for the formulas that effectively influence the depth, and empirical formulas are proposed. In this paper, some opinions are put forward on the growth and dissipation of pore water pressure under strong ramming action and the influence of vibration on nearby buildings. In addition, a preliminary discussion was made on the principle of the strong entrenchment method, and the application of the explosion comparison method in entrenchment was proposed.
