	<span style=\"font-size:12px;\">为了探究粉砂土的不同掺量对水泥基泡沫轻质粉土力学性能的影响规律，针对工程常用的湿密度为700 kg/m<sup>3</sup>的泡沫轻质粉土，通过开展室内试验，对水泥基泡沫轻质粉土在不同粉砂土掺量(20%, 30%, 40%)条件下的无侧限抗压强度、饱水抗压强度、弯拉强度和静弹性模量进行了测试分析。试验结果表明：随着粉砂土掺量的提高，无侧限抗压强度、弯拉强度和静弹性模量先增大后降低，最优掺量为20%；相较于无侧限抗压强度，饱水抗压强度降低幅度较大，且随粉砂土掺量增加而降低。<br />
In order to explore the influence of different dosage of silty soil on the mechanical properties of foamed mixture lightweight silty soil, in view of the foamed mixture lightweight silty soil with the wet density of 700 kg/m<sup>3</sup> commonly used in engineering, the unconfined compressive strength, saturated compressive strength, flexural tensile strength and static elastic modulus of foamed mixture lightweight silty soil with different silty soil content (20%, 30%, 40%) are tested and an-alyzed through laboratory tests. The test results show that the unconfined compressive strength, flexural tensile strength and static elastic modulus first increase and then decrease with the in-crease of silty soil content, and the optimal content is 20%. Compared with unconfined compressive strength, saturated compressive strength decreases significantly, and decreases with the increase of silty soil content.</span>
