1. Low strain yekuona nzira
Iyo yakaderera strain yekuona nzira inoshandisa nyundo diki kurova pamusoro pemurwi, uye inogamuchira masaini ekushushikana kubva pamurwi kuburikidza nemasensor akasungirirwa kumusoro kwemurwi. Mhinduro ine simba yemurwi-soil system inodzidzwa uchishandisa stress wave theory, uye kuyerwa kwevelocity uye frequency masaini anodzoserwa uye kuongororwa kuti awane kuvimbika kwemurwi.
Chiyero chekushandisa: (1) Iyo yakaderera strain yekuona nzira inokodzera kuona kutendeseka kwekongiri mirwi, seyakakandwa-mu-nzvimbo mirwi, prefabricated piles, prestressed pombi piles, simende inobhururuka madota marara, nezvimwe.
(2) Mukuita kwekuderera kwekuyedzwa, nekuda kwezvinhu zvakaita sekupokana kwevhu padivi remurwi, kunyorovesa kwemurwi zvinhu, uye shanduko mukuvharirwa kwechikamu chemurwi, kugona uye amplitude. stress wave propagation process inozoora zvishoma nezvishoma. Kazhinji, simba rekushungurudzika kwemhepo rakaora zvachose risati rasvika pasi pemurwi, zvichiita kuti kusakwanisa kuona chiratidzo chekuratidzira pasi pemurwi uye kuona kuvimbika kwemurwi wose. Zvinoenderana neruzivo chairwo rwekuyedza, zvakanyanyo fanira kudzikamisa kureba kwemurwi unoyerwa kusvika mukati me50m uye dhayamita remurwi hwaro kusvika mukati me1.8m.
2. High strain yekuona nzira
Iyo yakakwira strain yekuona nzira inzira yekuona kutendeseka kwemurwi hwaro uye yakamira inotakura kugona kwemurwi mumwe. Iyi nzira inoshandisa sando inorema inorema kudarika 10% yehuremu hwemurwi kana kudarika 1% yehuremu hwekutakura hwemurwi mumwe chete kudonha zvakasununguka uye kurova pamusoro pemurwi kuti uwane akakodzera dynamic coefficients. Chirongwa chakatemerwa chinoshandiswa pakuongorora uye kuverenga kuti uwane kutendeseka kweiyo pile nheyo uye vertical kutakura kugona kwemurwi mumwe. Iyo inozivikanwa zvakare seyo Nyaya nzira kana Cap wave nzira.
Chiyero chekushandisa: Iyo yakakwira dhizaini yekuyedza nzira yakakodzera kune mirwi nheyo dzinoda kuyedza kuperera kwemuviri wemurwi uye kuona iyo inotakura simba remurwi hwaro.
3. Acoustic transmission nzira
Iyo inonzwika wave yekupinda nzira ndeyekumisikidza akati wandei machubhu ekuyeresa mukati memurwi usati wadira kongiri mumirwi nheyo, iyo inoshanda senzira dze ultrasonic pulse transmission uye yekugamuchira probes. Iwo ruzha ma paramita eiyo ultrasonic pulse ichipfuura nepakati-chikamu chega chega inoyerwa poindi nepoindi pamwe neiyo longitudinal axis yemurwi uchishandisa ultrasonic detector. Zvadaro, dzakasiyana-siyana dzenhamba dzakatarwa kana kutongwa kwekuona kunoshandiswa kugadzirisa zviyero izvi, uye hurema hwemuviri wemurwi uye zvinzvimbo zvadzo zvinopihwa kuona chikamu chekuvimbika chemuviri wemurwi.
Chiyero chekushandisa: Iyo acoustic yekufambisa nzira inokodzera kuyedzwa kwekuvimbika kwekongiri yakakandwa-mu-nzvimbo mirwi ine pre embedded acoustic chubhu, kuona dhigirii rehurema hwemurwi uye kuona nzvimbo yavo.
4. Static load test nzira
Iyo pile foundation static load test nzira inoreva kuisa mutoro pamusoro pemurwi kuti unzwisise kupindirana pakati pemurwi nevhu panguva yekuita basa rekushandisa. Pakupedzisira, kunaka kwekuvaka kwemurwi uye kukwanisa kwekutakura kwemurwi kunotsanangurwa nekuyera maitiro eQS curve (kureva settlement curve).
Chiyero chekushandisa: (1) Iyo static mutoro yekuyedza nzira yakakodzera kuona iyo yakamira yekumanikidza inotakura simba remurwi mumwe.
(2) Iyo static mutoro wekuyedza nzira inogona kushandiswa kurodha murwi kusvika yatadza, ichipa imwechete murwi inotakura dhata redhizaini.
5. Drilling uye coring nzira
Iyo yepakati yekuchera nzira inonyanya kushandisa muchina wekuchera (kazhinji une dhayamita yemukati ye 10mm) kuburitsa masampuli epakati kubva panheyo dzemurwi. Zvichienderana neakabviswa musimboti samples, mitongo yakajeka inogona kuitwa pahurefu hwemurwi hwaro, simba rekongiri, sediment ukobvu pazasi pemurwi, uye mamiriro eiyo inotakura layer.
Kuyera kwekushandisa: Iyi nzira yakakodzera kuyera kureba kweakakanda-mu-nzvimbo mirwi, kusimba kwekongiri mumurwi wemurwi, ukobvu hwemashanga pazasi pemurwi, kutonga kana kuona dombo nevhu remurwi. kutakura layer pamagumo emurwi, uye kuona chikamu chekutendeseka chemuviri wemurwi.
6. Murwi mumwechete vertical tensile static load test
Iyo yekuyedza nzira yekuona inoenderana vertical anti kudhonza kutakura kugona kwemurwi mumwe ndeye kushandisa yakamira anti kudhonza simba nhanho nhanho kumusoro kwemurwi uye tarisa iyo anti kudhonza kusimuka kwemurwi wepamusoro nekufamba kwenguva.
Chiyero chekushandisa: Sarudza iyo yekupedzisira yakatwasuka tensile kutakura kugona kwemurwi mumwe; Sarudza kana iyo yakatwasuka tensile kutakura kugona inosangana nezvinodiwa zvekugadzira; Eresa lateral kuramba kwemurwi uchipokana nekudhonza-kunze kuburikidza nekuomesera uye kusimuka kwekuyedza kwemurwi wemuviri.
7. Single murwi horizontal static mutoro bvunzo
Iyo nzira yekuona yakachinjika kutakura kugona kwemurwi mumwe chete uye yakachinjika kuramba coefficient yenheyo ivhu kana kuyedza uye kuongorora yakachinjika kutakura kugona kweinjiniya mirwi uchishandisa chaiwo mamiriro ekushanda ari pedyo neyakachinjika mirwi inotakura. Iyo imwechete murwi yakachinjika mutoro bvunzo inofanirwa kutora iyo unidirectional yakawanda kutenderera kurodha uye yekuburitsa bvunzo nzira. Pakuyera kushushikana kana kuomeswa kwemuviri wemurwi, nzira inononoka yekugadzirisa mutoro inofanira kushandiswa.
Chiyero chekushandisa: Iyi nzira yakakodzera kuona yakachinjika yakakosha uye yekupedzisira kubereka kugona kwemurwi mumwe, uye kufungidzira ivhu rekudzivirira paramita; Sarudza kana iyo yakachinjika kutakura kugona kana kuchinjika kusimuka kunosangana nezvinodiwa zvekugadzira; Edza nguva yekukotama yemuviri wemurwi kuburikidza nekuomerwa uye kuyedza kusimuka.
