摘要

高分子材料SH固土剂与生石灰粉共同固化滨海盐渍土具有很高的抗压强度、抗拉强度和水稳性。由于SH固土剂对土颗粒的包裹作用及在土颗粒间和孔隙内形成的丝网状联接结构，使得固化土的强度和水稳性较单一石灰固化土提高很多，正弦波压缩疲劳作用降低了固化土的抗压强度。在一定的荷载值及幅值条件下，随疲劳次数的增加，抗压强度下降。30×103疲劳次数是强度下降的另一个起始点。固化土的微结构形貌照片显示，SH固土剂在两周固化龄期时形成了稳固的丝网状联接结构，四周龄期时结构已相当稳定。浸水后丝网状联接结构依然存在，表明SH固土剂的固化反应具有不可逆性。

Abstract

Solidified saline soil in inshore with polymer-SH agent and lime has a very high compression strength

tensile strength and stability in nature and after soaking in comparison with solidified soil only by lime because soil particles were enveloped by SH agent and formed web structure between particles and in voids. Compression strength of solidified soil decreased after applying sinusoidal load

and has some attenuation with the growth of fatigue times under a preload value and constant amplitude of load. Value 30×103 times is a special starting point from which strength falls. It has been certified that SH agent has made the stable web structure in soils when two weeks and it is better when four weeks with the help of observation of SEM’ pictures. This web structure remain stable after soaking

it is obvious that SH agent’s solidifying reaction is no reversibility in soils.
