With the increasing of bondstrength between soil particles, the initial elastic modulus and peak strength of talus deposit go up at a certain level.
随着土颗粒间黏结强度的提高，堆积体的初始弹性模量和峰值强度都有所提高。

To ensure that in the initial setting of concrete before the row on the lower bond, so as to safeguard the overall strength of concrete.
保证混凝土在初凝之前，上下层的连续粘接，以保障混凝土的整体强度。
