Method for improving horizontal displacement test precision of deep soil body
The invention discloses a method for improving the horizontal displacement test precision of a deep soil body. The method comprises the following steps of (1) arranging an inclinometer pipe in a deepsoil body to be tested, and enabling a gap to be formed between the inclinometer pipe and the deep soil body to be tested; (2) carrying out compaction grouting in the gap between the inclinometer pipeand the deep soil body to be tested, and ensuring that the gap is filled with a cement paste; (3) putting an inclinometer into the inclinometer pipe, and testing the horizontal displacement of the deep soil body to be tested. In the gap between the inclinometer pipe and a placing hole, the cement paste is extruded and filled by adopting the compaction grouting mode, the gap between the inclinometer pipe and the placing hole is completely filled after the cement paste is solidified, so that the measured data is ensured to reflect the actual horizontal displacement of the deep soil body, and the test precision is improved.
本发明公开了一种提高深层土体水平位移测试精度的方法，包括以下步骤：(1)将测斜管设置于待测深层土体中，所述测斜管与待测深层土体之间具有间隙；(2)在所述测斜管与待测深层土体之间的间隙中压密注浆，使得所述间隙中填充水泥浆；(3)将测斜仪放入测斜管中，测试待测深层土体水平位移。本发明在测斜管与放置孔之间的间隙中，采用压密注浆方式将水泥浆挤出并填充水泥浆，在水泥浆凝固后使得测斜管与放置孔之间的间隙完全填实，保证测出的数据反映实际的深层土体水平位移，提高测试精度。
