Then, the water-retention curve is employed to consider the coupling of suctions and stresses under constant water condition.
并利用土的持水曲线建立常含水量下吸力与土体应力之间的耦合作用关系。
In the lower soil suction range , The water-supply capacity of red soil derived from Q2 was higher than that derived from granite while In the higher soil suction range the different was not widely.
对于相同母质发育的红壤，在低吸力阶段，轻度侵蚀、中度侵蚀、重度侵蚀土壤的持水量相差不大；
In the lower soil suction range , The water-supply capacity of red soil derived from Q2 was higher than that derived from granite while In the higher soil suction range the different was not widely.
