As　a　new　support　structure　system,　the　double-row　pile　is　widely　used　in　foundations　in　pit　engineering,　slope　engineering,　water　conservancy　engineering,　and　other　fields.　It　has　a　big　horizontal　stiffness　and　strong　anti-overturning　ability　and　has　less　impact　on　the　surrounding　neighboring　existing　buildings　(structures)　when　it　is　applied.　It　must　be　mentioned　that　the　design　experience　of　the　double-row　pile　is　ahead　of　the　theory,　and　some　research　has　been　carried　out　on　double-row　pile　support　structures.　This　work　reviews　and　evaluates　the　force　deformation　and　earth　pressure　on　piles　of　double-row　piles,　including　pile　deformation　damage　mechanism,　soil　pressure　distribution　law,　and　double-row　pile　structure　form.　In　addition,　the　problems　and　shortcomings　of　the　current　double-row　pile　research　are　concluded.　These　results　have　enriched　the　study　of　the　mechanism　of　double-row　piles,　provided　the　theoretical　guidance　for　double-row　pile　support　structures,　and　laid　the　foundation　for　further　theoretical　research.
