loginAtu konklui Bazeia ba rezultadu Analiza Estabilidade ba Abutment Hasoru Presaun rai iha Ponte Futudo iha Município VIQUEQUE utiliza aplikasaun GEO5 iha STA: 55 + 286.60 mak hanesan:
a Rezultadu Kalkulasaun ba teste sondir todan 10-ton ho profundidade 9.2 m iha tabela no 4. Husi teste sondir terenu poin I ho nia klean 9.2m, klean husi 0.2 – 2.8m konsistensia rai hola parte tós(stiff), husi rai klean 3.0 - 3.2m konsistensia rai hola parte muito tós ituan (very stiff). Husi rai klean 3.4 – 6.0m konsistensia rai hola parte tós (stiff), husi rai klean 6.2 – 9.2m konsistensia rai hola parte tós los (hard). Tamba ne’e mak tama iha karakteristika rai Rai-henek (sands) ou rai ida ne’ebe mak tos.
b Rezultadu Analiza running software geo5 Standar safety factor ba abutment. Standar hirak ne’ebe foti hodi running abutment iha tolu (3) mak hanesan: safety factor ba overturnning 1.50, safety factor ba sliding resistance 1.50 no safety factor ba bearing capacity 3.0. Running software geo5 ba abutment hanesan: gama dry, gama saturation, cohesi of soil, angel friction internal, angel friction struc. Soil iha tabela no. 6. Dimensaun abutment refere ba medida no komparasaun geometriku husi estrutura suporta ponte iha fig. No. 4. Resultadu verifikasaun husi abutment resultadu ba active forces, passive forces, sliding moment, resisting moment no safety factor ba abutment ne’e rasik. Slope stability verification: sum of active forces Fa=1482.52 kN/m, Sum of passive forces Fp=2484.21 kN/m, sliding moment Ma=18368.45 KNm/m, Resisting moment Mp=30781.83 KNm/m, Factor of safety=1.68 > 1.50 (slope stability acceptable) Figura 6.
