为了改善高速公路路基强度,应用路基强夯法来提高路基抗压强度和减少工后沉降。在有效影响深度范围内采用公式计算得到强夯试验后的夯击能、压实度、夯沉量之间的关系,并用不同夯击能下的强夯试验来印证,最后得出利用强夯法进行路基的补强加固是有效的和夯击能、压实度、夯沉量之间的数值关系。
In order to improve the highway subgrade strength, the application of subgrade dynamic compaction method to improve the subgrade compressive strength and reduce post-construction settlement. In the range of the effective depth of influence, the relationship between the compaction energy, compaction degree and compaction volume after dynamic compaction test is obtained by the formula and confirmed by the dynamic compaction test with different compaction energy. Finally, it is concluded that the use of dynamic compaction Law reinforcement and reinforcement of the subgrade is effective and the impact energy, compaction, the amount of ramming between the numerical relationship.
