Accompanying drawing explanation
Fig. 1 is the structural representation that the utility model is built in the load-carrying members on high slope or complicated geology region.
In figure, be labeled as: load-carrying members body 1, load-bearing basis 2, girth member 3, petrographic province matrix 4, anchor bar bundle 5, external part 6, system anchor bolt 7, steel bar concrete panel 8, the section of stretching out 9, prestress anchorage cable 10, stretch out joint 11, foundation plane 12, initial land form line side slope face 13, grout hole 14.
The specific embodiment
Be as shown in Figure 1 the utility model a kind of Stability Analysis of Structures, the supporting capacity that provide strong be built in the load-carrying members on side slope or complicated geology region.Described load-carrying members comprise load-carrying members body 1, load-bearing basis 2 and the inner petrographic province matrix 4 that is provided with girth member 3, and the top on described load-bearing basis 2 is connected with described load-carrying members body 1, and bottom is connected with described petrographic province matrix 4; Described petrographic province matrix 4 is the cement-grouting consolidation body through the fixed formation of well cementing in complicated geological area or high slope region; Be arranged on one of girth member 3 in described petrographic province matrix 4 for the vertical anchor bar bundle 5 in described petrographic province matrix 4 that is arranged on, described anchor bar bundle 5 has an external part 6, and described external part 6 stretches in described load-bearing basis 2.Build described load-carrying members and comprise the following steps,
1) foundation excavation, according to drawing requirement, the selection area in complicated geological or high slope area adopts hand excavation or little dose blasting type excavation to form the foundation plane 12 on described load-bearing basis 2;
2) petrographic province matrix construction, the described foundation plane 12 forming after excavation finishes faces on sky side initial land form line side slope face 13, and the rock stratum to described foundation plane below 12 is implanted into girth member 3 and forms the petrographic province matrix 4 that contains described girth member 3;
3) petrographic province matrix 4 is fixed, after petrographic province matrix 4 has been constructed, the geological condition obtaining during according to foundation plane 12 excavation, on described foundation plane 12, in petrographic province matrix 4, be drilled with grout hole 14, and in described petrographic province matrix 4, carry out consolidation grouting construction by described grout hole 14, form the petrographic province matrix 4 of cement-grouting consolidation body structure, meanwhile to inserting anchor bar bundle 5 in described grout hole 14, form multi-column pier foundations and complete the fixed of petrographic province matrix 4;
4) construction of load-bearing basis 2 and load-carrying members body 1 be take foundation plane 12 as basal plane on described petrographic province matrix 4, carries out respectively from lower to upper the pouring construction of load-bearing basis 2 and load-carrying members body 1 concrete, has so just completed the construction of described load-carrying members.
By first selection area in complicated geology or high slope area, excavate out foundation plane 12, then at described foundation plane 12, face on sky side initial land form line side slope face 13, rock stratum to foundation plane below 12 is implanted into girth member 3 and forms after the petrographic province matrix 4 that contains described girth member 3, the geological condition obtaining while excavating according to foundation plane 12 on described petrographic province matrix 4 again, be drilled with grout hole 14, and carry out consolidation grouting and insert anchor bar bundle 5 in described petrographic province matrix 4 by described grout hole 14, formation has the petrographic province matrix 4 of the cement-grouting consolidation body structure of multi-column pier foundation, finally on the petrographic province matrix 4 of the described cement-grouting consolidation body structure with multi-column pier foundation, build successively load-bearing basis 2 and load-carrying members body 5 concretes, form described load-carrying members.Like this, owing to being provided with the girth member 3 that can effectively improve described petrographic province matrix 4 stability and supporting capacity in the petrographic province matrix 4 described, thereby make also there is very strong stability and supporting capacity take the described load-carrying members that described petrographic province ground matrix 4 is foundation construction one-tenth.
Above-mentioned executing in mode, being arranged on one of girth member 3 in described petrographic province matrix 4 can be the system anchor bolt 7 in described petrographic province matrix 4 that is arranged on tilting, also can be the prestress anchorage cable 10 in described petrographic province matrix 4 that is arranged on tilting, can also be tilt be arranged on described system anchor bolt 7 in described petrographic province matrix 4 and the combination construction of prestress anchorage cable 10.Simultaneously, in order to make described petrographic province matrix 4 can not go out collapsing and/or coming down of original side slope under adverse weather condition, in setting, complete after described system anchor bolt 7 and/or prestress anchorage cable 10, on described petrographic province matrix 4 outside initial land form line side slope faces 13, also build steel bar concrete panel 8 thereupon, make the section of stretching out 9 and/or the stretching out of prestress anchorage cable 10 of described system anchor bolt 7 save 11, insert respectively in described steel bar concrete panel 8, like this, even under harsh climate condition very, the phenomenon that described initial land form line side slope face 13 also can not go out to collapse and/or come down owing to there being the protection of steel bar concrete panel 8.Further guaranteed the stability of described load-carrying members.
