　　SL-80原位壓力機測定方法：

　　1、先在墻體上開鑿兩條水平槽孔①上水平槽尺寸應為240mm×250mm×70mm(深×寬×高)②下水平槽尺寸為240mm×250mm×140m(深×寬×高)，(下槽的高度視壓力機型號不同而調整)③上下水平槽孔對齊，兩槽間相隔7皮磚，凈距約430mm④槽間砌體的承壓面修平整

　　2、安放原位壓力機①在上槽下表面和扁式千斤頂的頂面，均勻鋪設厚10mm濕細砂墊層或石膏等其他材料，便于均勻受力②將反力板置于上槽孔及扁式千斤頂置于下槽孔，并使兩個承壓板上下對齊后，擰緊螺母并調整其平行度

　　3、試加荷載檢查測試系統是否靈敏以及上下壓板和砌體受壓面接觸是否均勻密實，待正常后卸荷即開始測試。4、正式測試分級加荷，每級荷載約為預估破壞荷載的10%，加至預估破壞荷載的80%，連續加荷直至槽間砌體破壞(當槽間砌體裂縫急劇擴展而壓力表指針明顯回退時，即為槽間砌體的破壞荷載)。

　　5、將破壞荷載換算成槽間砌體的抗壓強度和標準砌體抗壓強度，再與設計值對比，從而判明現有砌體的真實強度。

　　6、數據分析。

　　SL-80 in-situ press determination method:

　　1.First cut two horizontal slot holes in the wall.①The upper horizontal slot size should be 240mm×250mm×70mm(depth×width×height).②The lower horizontal slot size should be 240mm×250mm×140m(depth×width×high).,(The height of the lower groove is adjusted according to the type of the press)③The upper and lower horizontal grooves are aligned,ａnd the two grooves are separated by 7 leather bricks with a clear distance of about 430mm.

　　2.Place the in-situ press①On the lower surface of the upper groove and the top surface of the flat jack,evenly lay a 10mm thick wet sａnd cushion or gypsum and other materials to facilitate uniform stress②Place the reaction force plate in the upper groove hole And flat jack are placed in the lower slot,ａnd the two pressure plates are aligned up and down,tighten the nut and adjust its parallelism

　　3.Trial load test Check whether the test system is sensitive and whether the upper and lower pressure plates and the contact surface of the masonry are uniform and dense.After the load is normal,the test is started.4.Formal test of formal loading,each load is about 10%of the estimated damage load,added to 80%of the estimated damage load,ａnd continuously loaded until the masonry between the grooves is damaged When the pointer of the pressure gauge retreats obviously,it is the damage load of the masonry between the grooves).

　　5.Convert the damage load into the compressive strength of the masonry between the grooves and the compressive strength of the standard masonry,ａnd then compare it with the design value to determine the true strength of the existing masonry.

　　6.Data analysis.
