for the gaomiaozi bentonite tested here, there is an exponential relationship between swelling pressure and dry density; and dry density is an important factor influencing swelling pressure.
高压实高庙子膨润土的膨胀力和干密度之间存在指数关系,干密度是影响膨胀力的一项重要的因素。
by using the rmt-150b servo rock testing system, we have performed uniaxial compression test and analysed mechanical parameter of swelling pressure at different water contents.
on this foundation, the determination method of treatment depth for subgrade paved with expansive soil is proposed based on the relationship of swelling pressure and unloaded expansibility.
在此基础上,建议按膨胀力与零膨胀率的相关性来确定膨胀土路基处置深度。
a large scale model test was carried out to study the variation of lateral swelling pressure of expansive soil acting on retaining wall due to deep inundation.
通过大型模型试验,研究了深层浸水条件下膨胀土挡墻侧向膨胀压力的变化规律。
it is understood that the existence of large amount of swelling pressure in the slope due to rainfall changes the expansive soil slopes' stress and strain distribution.
膨胀土路基边坡在持续降雨后常常出现大面积表层滑坍失稳 ,造成巨大的经济损失。
the equilibrium time of the maximum swelling pressure relates to the dry density, while the initial suction does not play an important role in it.
⑤膨胀力最终平衡时间随干密度增大有所增加,而初始吸力对平衡时间影响不大。
a site including expansive soil layer with high swelling pressure is chosen to illustrate the influence of thickness and position of expansive soil layer on upheaval deformations.
compared with the higher suction specimens, the development rate of swelling pressure of specimens with the lower suction is inferior at early stage, but it becomes superior after a period of time.
evolution of the swelling pressure is affected by both the dry density and the initial suction of the specimens.
③初始吸力、干密度均会显着影响膨胀力随时间变化曲线的形状;
a formula of fluid swelling pressure (fsp) has been presented under the conditions of hypothesis testing in combination with the data collection in geothermal-geological fieldwork.
