湿陷性黄土在我国分布广泛，也是经常遇到的地基土层，性质受其结构的影响较大。取土方法是扰动其结构的重要因素之一，运用不当会造成人力和经济上的损失。本文运用工程实例，对钻孔和探井两种取土方法所获得的压缩模量进行比较后发现，在不同的取土深度下，钻孔压缩模量的最大值、最小值和平均值普遍大于探井压缩模量；钻孔法和探井法的压缩模量最大值、最小值和平均值的比值均随深度的增加而减小，当达到一定深度时两者趋于一致，而这种关系和湿陷性程度在深度上的分布一致。

Col apsible loess is widely distributed in our country, and is frequently meet with foundation soil. Its nature is strongly influenced by its structure. Removal method is one of the important factors of disturbance in the structure, improper use can cause the human and economic losses. In this paper, using the engineering example, the dril ing and exploration Wel s obtained by the two methods of soil compression modulus are compared and found under the dif erent soil depth, dril ing compression modulus maximum, minimum and average general y greater than the compression modulus of Wel s; Dril ing method and exploration method of compression modulus maximum, minimum and average ratio decreases with the increase of the depth, when reaching a certain depth both converge, and the relationship between degree of col apsibility and in depth the distribution agreement.
