This　paper　introduces　a　method　which　utilizes　global　navigation　satellite　system　(GNSS)　based　precision　point　positioning　(PPP)　for　conducting　long-term　tilt　and　settlement　monitoring　of　high-rise　buildings　in　North　China.　Two-year　continuous　GNSS　observations　from　two　high-rise　buildings　near　a　deep　foundation　pit　in　Beijing　are　used　for　the　case　study.　The　method　comprises　four　steps:　Calculating　the　geocentric　coordinates　(XYZ)　of　the　GNSS　antenna　with　respect　to　a　global　reference　frame　(e.g.,　IGS08)　with　the　PPP　method;　transforming　the　geocentric　coordinates　to　a　regional　reference　frame-the　North　China　reference　frame　(NChina16);　converting　the　geocentric　XYZ　coordinates　to　a　station-centric　East　-North-Up　(ENU)　coordinates;　removing　seasonal　ground-surface　deformation　from　the　ENU　time　series　and　restoring　the　true　displacements　(tilt　and　settlement)　of　the　building.　Experimental　result　indicates　that　the　PPP　method　is　able　to　achieve　2-3　mm　horizontal　accuracy(root　mean　square　error)　and　6-9　mm　vertical　accuracy　(root　mean　square　error)for　24-hour　continuous　observations　in　North　China.　The　combination　of　PPP,　NChina16,　and　the　North　China　seasonal　ground　deformation　model　can　perform　millimeter-accuracy,　near-real　time,　and　long　term　static　structural　health　monitoring　of　high-rise　buildings　and　other　large-scale　infrastructure　projects　in　North　China.　©　2020,　Editorial　Board　of　Geomatics　and　Information　Science　of　Wuhan　University.　All　right　reserved.
