1. Kugadzira hafu yakazadzwa nehafu yakacherwa mabhedhi emigwagwa
Paunenge uchigadzira materu pamateru ane chitubu chakadzika kupfuura 1: 5 pasi, matanho anofanirwa kucherwa pazasi pemushonga, uye hupamhi hwematanho hahufanire kunge huri pasi pe1 mita. Pakugadzira kana kugadziridza migwagwa mikuru mumatanho uye kuwedzera, matanho anofanirwa kucherwa panosangana nhungirwa nyowani neyekare inozadza materu. Hupamhi hwematanho mumigwagwa mikuru-giredhi kazhinji 2 metres. Mageogrid anofanirwa kuiswa pamusoro penzvimbo yakachinjika yenhanho imwe neimwe yematanho, uye yakamira yakatwasuka yekuvharirwa mhedzisiro yeiyo geogrids inofanirwa kushandiswa kugadzirisa zvirinani dambudziko rekugadzirisa zvisina kuenzana.
2. Mugwagwa munzvimbo dzine mhepo uye dzine jecha
Mubhedhi wemumugwagwa munzvimbo dzine mhepo uye dzine jecha dzinofanirwa kunyanya kuve nedzakadzika, nehurefu hwekuzadza kazhinji husingasviki 0.3M. Nekuda kwehunyanzvi hunodiwa kune yakaderera embankments uye inorema kutakura simba mukuvaka ebankments munzvimbo dzine mhepo uye dzine jecha, kushandiswa kwema geogrids kunogona kuve ne lateral kuvharirwa mhedzisiro pane akasununguka mafirita, kuve nechokwadi chekuti mugwagwa une kuoma kwakanyanya uye simba mukati mehurefu hushoma. kutsungirira mutoro wekushushikana kwemotokari huru.
3. Kusimbiswa kwevhu rekuzadza kumashure kwemupendero
Kushandiswa kwegeogrid chambersinogona kuita zvirinani chinangwa chekusimbisa kumashure kwebhiriji. Iyo geogrid kamuri inogona kuunza kukweshera kwakakwana pakati pezvinhu zvekuzadza, zvichinyatso kudzikisa kusawirirana pakati pemugwagwa uye chimiro, kuitira kuti zvinyatso kudzikamisa kukuvara kwekutanga kwechirwere che "bridge abutment jumping" padhiza rebhiriji.
4. Kurapa kweLoess Collapse Roadbed
Kana migwagwa mikuru nemigwagwa yakajairwa ichipfuura nemuzvikamu zvinorasika uye zvakarasika zvine kusimba kwakanaka, kana kana iyo inobvumirwa kutakura hwaro hwehwaro hwepamusoro yakadzikira pane kudzvanywa kwemotokari yemubatanidzwa uye uremu hwehuremu, mubhedha wemugwagwa unofanirwawo kurapwa zvinoenderana iyo inotakura kugona zvinodiwa. Panguva ino, hukuru hwepamusorogeogridinoratidzwa pasina mubvunzo.
5. Saline ivhu uye expansive ivhu
Mugwagwa mukuru wakagadzirwa nevhu resaline uye ivhu rakakura unotora matanho ekusimbisa mapendekete uye materu. Iyo vertical reinforcement effect yegridi yakanakisa pakati pezvese zvekusimbisa zvinhu, uye ine yakanakisa corrosion resistance, iyo inogona kuzadzisa zvizere zvinodiwa pakuvaka migwagwa mikuru muvhu resaline uye ivhu rakawedzera.
