Landslide test device considering arch effect of soil behind slide-resistant pile and use method of landslide test device
The invention discloses a landslide test device considering an arch effect of soil behind a slide-resistant pile and a use method of the landslide test device. The method comprises the following steps of 1) leveling a test bed and a test groove; 2) adjusting an included angle between a slot and the test groove according to test requirements; (3) inserting a plurality of model piles into the slot; 4) setting the test stroke of a jack; 5) preparing a soil sample and filling the soil sample into the test groove; 6) connecting a soil pressure sensor to a data acquisition device and a terminal; 7) adjusting the inclination of the test groove to a preset value; 8) starting the jack, and pushing a push plate and the soil sample; and 9) sending the acquired information to the data acquisition device and a terminal for analysis and processing through the soil pressure sensor. By means of the method, the soil slope instability process under the conditions of different slope angles, different soil and stone material types, different water contents and different grading can be visually represented, the soil slope instability process under the different slide-resistant pile supporting and retaining conditions can be visually represented, the supporting and retaining effect of the slide-resistant piles is evaluated, and the requirement of a model test is well met.
本发明公开了一种考虑抗滑桩后土拱效应的滑坡试验装置及其使用方法，该方法包括以下步骤：1)将试验台和试验槽调平；2)将插槽与试验槽之间的夹角按试验要求调整；3)将若干模型桩插入插槽内；4)设定千斤顶的试验行程；5)制备土样并填筑到试验槽内；6)将土压力传感器接线至数据采集装置及终端；7)将试验槽的倾斜度调整到预定值；8)启动千斤顶，推动推板和土样；9)土压力传感器将采集的信息发送至数据采集装置及终端进行分析处理。本发明能够直观再现不同坡角、不同土石料类型、含水率、级配条件下的土质边坡失稳过程，能够直观再现不同抗滑桩支挡条件下的土质边坡失稳过程，并对抗滑桩的支护效果进行评价，很好的满足模型试验的要求。
