Ma ke kahua o ke ana pololei o kēia au, ʻo ka mīkini ana lōʻihi, ma ke ʻano he mea nui, he mau koi kiʻekiʻe loa no ka pololei a me ke kūpaʻa. ʻO nā ʻāpana Granite, me ko lākou mau pono kūikawā, ua lilo i koho kūpono no nā mīkini ana lōʻihi, ʻoi aku ka maikaʻi i ka hana seismic.
Mai ka manaʻo o nā waiwai o nā mea, he pōhaku igneous ka granite i hana ʻia e ka hui pū ʻana o nā kristal mineral like ʻole. Ua ulana ʻia nā ʻāpana mineral kūloko kekahi i kekahi, e hana ana i kahi ʻano paʻa loa. Hāʻawi kēia ʻano paʻa i ka granite me ka paʻa a me ka ikaika kiʻekiʻe loa, e hiki ai iā ia ke mālama i kahi ʻano paʻa i nā wahi hana paʻakikī. Ke hana ʻia nā haʻalulu o waho, hiki i nā ʻāpana granite ke pale aku i ka deformation ma ka hilinaʻi ʻana i ko lākou paʻa ponoʻī, e hōʻemi ana i ka hoʻopilikia ʻana o nā haʻalulu i ka pololei o ke ana ʻana o ka mīkini ana lōʻihi. No ka laʻana, ma kekahi mau hale hana hana ʻoihana, ʻo ka hoʻomaka pinepine ʻana a me ka hoʻōki ʻana o nā lako a puni e hiki ke hana i nā haʻalulu. ʻO nā ʻāpana o ka mīkini ana lōʻihi i hana ʻia me nā mea maʻamau e maʻalahi i ka neʻe iki ʻana a i ʻole ka deformation ma muli o nā haʻalulu, kahi e hoʻopilikia ai i nā hopena ana. Eia naʻe, ma muli o kona pono paʻa, hiki i nā ʻāpana granite ke hōʻemi i kēia hopena.
ʻO ke ʻano damping kiʻekiʻe o ka granite kekahi o nā kumu nui no kāna hana seismic kiʻekiʻe. ʻO ka damping e pili ana i ka hiki o kahi mea ke hoʻopau i ka ikehu a hoʻemi i ka amplitude o ka haʻalulu i ka wā o ke kaʻina hana haʻalulu. ʻOi aku ka kiʻekiʻe o ka ratio damping o ka granite ma mua o nā mea metala he nui a me nā pōhaku maʻamau ʻē aʻe. Ke hoʻouna ʻia ka haʻalulu i ka ʻāpana granite, hiki i ke ʻano kristal i loko ona ke hoʻololi i ka ikehu haʻalulu i nā ʻano ikehu ʻē aʻe e like me ka ikehu wela a hoʻopau koke iā ia. Ua like kēia me ke kau ʻana i kahi mea hoʻopau haʻalulu ʻike ʻole ʻia ma ka mīkini ana lōʻihi, hiki ke hoʻēmi koke i ka haʻalulu a hiki i ka mīkini ana lōʻihi ke hoʻi koke i kahi kūlana paʻa i kahi ʻano haʻalulu. E lawe i ka hale hana hana mīkini kikoʻī ma ke ʻano he laʻana. ʻO ka hana wikiwiki o nā mea hana mīkini e hoʻoulu i nā haʻalulu ikaika. Inā hoʻohana ka mīkini ana lōʻihi i nā ʻāpana granite, hiki nō iā ia ke mālama i ke ana paʻa i loko o ia ʻano a hōʻoia i ka pololei o ka ʻikepili ana.
Ke hoʻohālikelike ʻia me nā mea ʻē aʻe, loaʻa i nā ʻāpana granite nā pono maopopo e pili ana i ke kūpaʻa ʻana i ka ōlaʻi. ʻOiai he ikaika kiʻekiʻe nā mea metala, ʻaʻole pinepine ka maikaʻi o kā lākou hana damping. Ke hoʻokuʻu ʻia i ka haʻalulu, loaʻa iā lākou nā oscillations mau e paʻakikī ke emi koke. ʻOiai kekahi mau mea synthetic e loaʻa paha kekahi mau hopena omo haʻalulu, ʻaʻole hiki iā lākou ke hoʻohālikelike me ka granite ma ke ʻano o ka paʻakikī a me ke kūpaʻa lōʻihi. Hoʻohui maikaʻi nā ʻāpana Granite i nā ʻano o ka paʻakikī kiʻekiʻe a me ka damping kiʻekiʻe. ʻAʻole hiki iā lākou ke mālama wale i ke kūpaʻa o ka hale i ka wā e hana ai ka haʻalulu, akā hoʻopau koke i ka laha a me ke kūpaʻa o ka haʻalulu.
Ma nā noi hana, ua hōʻike nā mīkini ana lōʻihi e hoʻohana ana i nā ʻāpana granite i ka hana koʻikoʻi ma nā ʻano he nui. I ka hana ʻana o nā ʻāpana aerospace, he mea nui nā mīkini ana lōʻihi kiʻekiʻe no ka hōʻoia ʻana i ka pololei o nā ana o nā ʻāpana. ʻO ka hana seismic o nā ʻāpana granite e hiki ai i ka mīkini ana lōʻihi ke hana paʻa i nā wahi hana paʻakikī, e hāʻawi ana i kahi hōʻoia paʻa no ka kaohi maikaʻi o nā ʻāpana aerospace. Ma ke kahua o ka hana ʻana i nā mea hana optical, ʻo ka pololei o ke ana ʻana o nā ʻāpana optical pololei e like me nā aniani e hoʻopilikia pololei i ka maikaʻi o ke kiʻi o ka mea hana. ʻO ka hoʻopili ʻana o nā ʻāpana granite e hōʻemi pono i ka hoʻopilikia ʻana o nā haʻalulu o waho ma ke ana ʻana, e kōkua ana i ka hana ʻana o nā mea hana optical e hoʻokō i ka pololei kiʻekiʻe.
ʻO nā ʻāpana Granite, me kā lākou hana seismic maikaʻi loa, ua lilo i mea nui no nā mīkini ana lōʻihi e hoʻonui i ka pololei a me ke kūpaʻa o ke ana ʻana. Me ka hoʻomohala mau ʻana o ka ʻenehana ana pololei, e ʻoi aku ka laulā o nā manaʻolana noi o nā ʻāpana granite i nā mīkini ana lōʻihi a me nā lako ana pololei, e hāʻawi mau ana i ke kākoʻo hilinaʻi no ka hana ʻana i nā ʻoihana like ʻole.
